visitors: Thanks for coming by. If you’ve experienced the problem described below, please leave a comment and Digg this story. Dell is aware of the problem identified here, but rather than take the proactive step of notifying customers who purchased susceptible systems — namely, data loss and/or a system crash from which you potentially cannot recover — they are addressing the problem only too late: when people call to report the problem.
This thread contains hundreds of comments now, some of which ultimately describe a different problem than the one originally addressed here. In short, IASTOR.SYS is a disk controller driver. Older versions of it are susceptible to errors which can cause problems with your hard drive(s).
Update in June 2008: This post has steadily drawn over 10,000 visits per month for the last year. Dell, if you’re out there and you’d like me to link to some concise troubleshooting information on your site, please email me at ydeologi [at] gmail [dot] com.
Summary as of 12/28/06: IASTOR.SYS is a driver provided by Intel to Dell as an interface to the on-board Intel storage controller used on motherboards in Dell computers. Simply put, it is software that allows Windows XP to communicate with a computer’s hard drive. Since I posted this article in April, I’ve had over 6,000 hits specifically on this topic, all from people researching the same basic problem I encountered early this year. Some salient points:
- So far, it has only been reported as a problem in Dell systems; I don’t know if the driver is being used in other manufacturers’ systems, but I suspect that if it is, the version being provided to Dell by Intel is different.
- This problem has been reported on many of Dell’s desktop product lines, so it is not limited to one type of system.
- Sometime in late 2005/early 2006, Dell began offering an option called “DataSafe”, where a PC is shipped with two hard drives arrayed in what’s called a RAID mirror; each hard drive contains an exact copy of the other so that in the event that one fails, the other lives on (and your data with it). To implement this, a few RAID compatible components are needed: the disk controller, the system BIOS, and a Windows device driver. RAID is very old, tested technology; the only new concern here is Dell’s use of it in their home market PCs. From what I’ve observed, the problem certainly seems to be most common in systems shipped with DataSafe enabled, but because the new device driver for the controller is also used for systems that weren’t ordered with the DataSafe option, the problem can show up for systems without DataSafe as well.
- It has been reported as a conflict with many different system devices, but especially video cards, sound cards, and network interfaces.
- Manufacturers like Dell depend on their suppliers to provide both reliable hardware components and software drivers to operate them. But companies like Dell are also responsible for testing the reliability of such components and their interoperability prior to releasing them for sale.
- Systems with bad drivers have been reportedly shipped as early as January 2006 and as late as October 2006.
- If this is, in fact, a problem for every Dell system shipped with IASTOR.SYS this year, then even after Dell and Intel work out a patch, it will have to be installed on every affected computer, or those computers will remain at risk for data loss and system failure.
- Intel released updated drivers in May 2006 which many have reported fix the problem, but Dell had not updated the drivers on their own website until posting a solution in late October/early November 2006. It is possible that even the drivers Intel posted in January fixed this issue, but that is not confirmed.
begin original story: If you have a Dell Dimension E510 or 5150 purchased in the last few months, you may experience a BSOD (blue screen of death) error in Windows XP related to a resource sharing conflict. I’ve read about errors related to IASTOR.SYS, an SATA controller driver, coming up a few different ways, but never quite in the way I saw it recently: under Windows XP Media Center with an SATA RAID mirror and an ATI TV Tuner add-on card.After the Windows splash screen, you’ll get a BSOD with a DRIVER_IRQL_NOT_LESS_OR_EQUAL error focusing on IASTOR.SYS, probably with stop code 0x000000D1. After enough reboots, the system might not even show the blue screen error, just reboot. Safe Mode doesn’t load the OS, either — just reboots. Booting into a recovery console is not helpful for rebuilding. Trying to update the IASTOR driver (which pertains to system with the 82801GR chipset, or related) manually without the OS accomplishes nothing.
Dell’s support technicians only recommend backing up your data and reinstalling. I usually don’t spend a lot of time, if any, calling Dell’s horrible level 1 support, but I thought I’d try a few times over a few days (even after I had it fixed) to see if some were better than others. (A note about Dell support: their Silver/Gold technicians are fantastic, but the Average Joe with an E510 won’t have access to them.)
The fix in this case: Open up the computer and remove the TV Tuner add-in card. That will alleviate the resource sharing conflict and allow the system to boot normally. Download and install D5150A05.EXE from Dell (a BIOS update that came out earlier this month). Also download R114566.EXE, which will update/reinstall your chipset drivers. After implementing both of those updates, put the TV Tuner add-in card back into the system and power back up. The system should work normally.
All in all, this is pretty routine troubleshooting; I won’t often post about fixes for specific issues, but I’m curious to see how many people are searching on the net for this particular problem. If you do post here about your experience, please be sure to include the date you purchased your system; I’m curious if they’re still shipping new systems with this problem.
Update 5/15/06: Turned out that wasn’t the end of the road. About a week later, trouble resurfaced when one of the drives in the RAID experienced corruption. Dell shipped out a replacement HDD which I’ve installed but have yet to incorporate into the RAID as yet. Right now, the system is using just one of the two drives, seemingly without incident. I don’t have a lot of confidence that rebuilding and using a RAID mirror will work properly until I see a new driver posted on their website. In any event, the BIOS update probably didn’t do anything except remap resources long enough for the system to boot… only for the resource conflict to re-emerge shortly thereafter.
Update 6/5/06: After hours of wasted time on the phone with technical support, explaining the problem and the process over and over again, not to mention transfers into supervisor queues only to languish on hold and eventually be disconnected… this system has been accepted for a free return and exchange by Dell’s Escalation team. A couple hundred people have searched the net for this problem and found this site. I wonder how many are having this problem, and I wonder if the “identical replacement system” they send out will have updated drivers or different hardware.
Update 7/3/06: I’ve yet to find any official word from Dell commenting on their awareness of this problem, but reports of the problem are out there everywhere. This must be a massive support headache for them. I have a few clients with the problem who have received replacement machines and have yet to experience any trouble; soon, I’ll post whether they replaced the offending hardware component, or if there’s a driver or BIOS update on these new machines that’s solved the problem. There aren’t any updated drivers on the Dell support site, from what I can tell.
Update 7/15/06: As you can see from the comments, a Dell technician has dropped by the site while searching for a solution to this problem. They don’t have a solution in the Dell Knowledge Base, but at least we can confirm they’re aware of the issue now; hopefully, they can work something out with Intel quickly.
Update 7/30/06: Amazingly, months later, Dell still lists the old, broken drivers on their website. As many readers have reported, using an updated Intel driver seems to repair the problem. This isn’t a Dell supported driver, but then, their supported driver is broken.
Update 10/11/06: A great post today from Edd gives hope that people experiencing this problem might not have to repair the IASTOR driver to correct this problem. (This is especially good news for people who are already experiencing the problem and can’t boot the OS.) I haven’t tested it yet, but it’s the kind of thing that shouldn’t cause any harm. When you first boot the computer, when the Dell logo appears, hold down the F2 key to enter the BIOS. Go to the section for your hard drives, and change the SATA operation type to “COMBO” instead of “RAID”. These instructions aren’t exact because I don’t have a Dell BIOS in front of me to check it, but I’ll try to test and post step-by-step shortly.
Update 11/9/06: Someone from Dell support has kindly posted a Dell support document in the comments below. It looks like they’ve gotten around to addressing the problem. While this won’t help all of the people whose systems have shipped with the problem until they run into it, at least they’re aware of it now.
I have a HP Pavillion dv6102od laptop. I updated my chipset and have been having issues with bsod iastor.sys…. I have followed all information so far provided for my system. Nothing has helped as of yet. The only reason I am posting, is because it seems to only happen to DELL. But I have an HP and am very confused why I am having this problem.
I have a Dell Dimension 8400 and suddenly, after several years with no problems, my system reboots itself. The error report says it is in iastor.sys, the RAID controller driver, but I don’t have a RAID system installed. When I download the driver it points to, it says my system doesn’t meet the minimum standards to install the driver. Now what?
Vlad’s three-part fix solved my problem. I was getting BSOD on virus scan, defrags or chkdsk.
hello,
i have the same problem!
my computer is a dell demontion e510.
purchased about 2 years from now.
i have tried fixing it by removin the tv card,
and tryna see if it starts from there.
but no good!
still gives me the blue screen!!
..
please help!
email me asap!
No solution for my case since my last post.
IASTOR Error on System Events during DEFRAG and sometimes from intensive files reading .
Buying a raid controller can solve the problem?
(is the IBM integrated controller [ICH8] controlling the additional controller?)
Just happened to find this website. I bought a Dimension E510 8/11/06. I work at home on my computer. It has always crashed periodically with the blue screen and something about a driver. Don’t exactly remember what all it says. Sometimes it is a few weeks in between crashes and other times it can do it a couple of times a day. I just reboot and recover the document I was working on. I haven’t had time to really pursue this problem which is just a huge annoyance because I haven’t really “lost” anything. When I have time, I will try one of these solutions.
*****Fix??***

Thanks, this solved my problem!
Dell XPS 400 DXP051, Windows Xp, w/ Hitachi Deskstar E7K500 500GB HD. About 2 yrs old.
While booting, received blue screen error:
DRIVER_IRQL_NOT_LESS_OR_EQUAL
Tech info: STOP 0X000000D1 (0X0000001B,

B9E36000, DateStamp 42b2df42
Following DELL XPS L2 11.07.06 and Ian 04.13.08 contributions, I solved the problem, but had to following slightly different repair procedures.
1] Booted into BIOS (w/ F2) and changed SATA Operations from AHCI to ATA.
2] Downloaded the Intel Matrix Storage Driver (ft://ftp.us.dell.com/SATA/R120119.EXE), but when I attempted to install it I received message: This computer does not meet minimum requirements for installing this software.:
3] Rebotted into BIOS and changed SATA Operations back to AHCI.
4] Re attempted installation of the Intel driver, with success.
5] Ran CHKDSK, which took forever, it didn’t hangup (as it had before installing the Intel driver), and resulted in a repaired & clean HD.
It now appears the problem is resolved!
See DELL XPS L2 11.07.06 (above) for detailed instructions on the procedures.
I Have a Dell XPS 410 for just under 2 years. My son was playing Fallout3 and he got the blue screen and just turned off the pc. Now we are unable to boot the pc. When we turn on the power, all we get is a black screen for about 5 min and then we get a mouse pointer arror followed by the hourglass for about 45 min. Finally we get a blue screen with the following error.
Stop: 0x0000007E (0xC0000005, 0xF745FA42, 0xF7AD7BAC, 0xF7AD78A8)

I am unable to boot into safe mode, or even try a factory O/S reinstall. Our system does NOT have a TV tuner card. Any help would be greatly appreciated. send a reply via email to jmamax1@yahoo.com
Great work, we’ve not only used this to resolve the problem with one of our customers, but have setup Kaseya to discover and automatically upgrade the drivers on affected systems.

Same problem (BSOD 0x000000D1 for IASTOR.SYS).
Solved it using the link from Andy Suarez (03.13.09 / 8pm). Dell recommended procedure didn’t work (as John pointed out on 3/22). John’s method works but he didn’t mention to boot into Safe Mode and install the driver under AHCI. I was unable to boot into XP under AHCI, but Safe Mode worked.
I got this error after Norton performed a full scan on my system and found & solved several issues. I don’t know if that had anything to do with it, but Norton required a restart and that was when I got the BSOD.
I owe this forum! I experienced the BSOD on my Dell XPS 400 series that has performed rather well since 2006 after installing some recommended Windows upgrades. Specifically, Driver_IRQL_NOT_LESS_OR_EQUAL Stop: 0x000000D1 (0×00000018, 0×00000002, 0×00000000, 0xF73AF25F) iastor.sys address F73AF25F base at F73A0000, datestamp 42b2df42. In short order, I could not boot to safe mode, and was considering restoring the PC (as per my Dell service tech rep). After reading all the posts on this forum, I followed one of the solutions and changed the SATA option in ‘setup’ to the ‘ATA’ option. As advertised, the machine booted to a normal appearing desktop. After resoring the system to before the date of the upgrade installation and after running CHKDSK and downloading Intel@Matrix Storage Driver file from ftp://ftp.us.dell.com/SATA/R130119.EXE, I booted to setup once again and restored the SATA setting back to the default (Autodetect/AHCI). Booted up again and installed the R130119.EXE driver file. NOTE: I was not able to install the updated driver until after restoring the SATA setting to the default – got an error code that ‘my computer was not configured….etc.’. After restoring the default SATA setting, the installation went smoothly, and I am back in business thanks to the many posts submitted by my fellow Dell victims. I hope that this will work for some of you.
Followup: Interestingly enough, after taking the steps outilned in my previous post, I searched for the file ‘iastore.sys’ but the search did not find it. After 24 ours, my computer is performing as normal. Thanks again to all – especially to post 131 ‘Dell XPS L2 11.07.06′.

I have a Dell Inspiron 1525 acquired in May 2008.
Two days ago, on April 28 2009, I had an almighty system crash, and received this error message:
Download and install the driver for your RAID controller
This problem was caused by your RAID controller, which was created by Intel Corporation.
The model name of your RAID controller is Intel Matrix Storage Manager (iaStor.sys).
Solution
To download and install the driver for your RAID controller, go online and follow the instructions on the manufacturer’s website:
Intel Corporation
I tried to follow these instructions, but my computer has not been functioning as usual ever since this crash!
Firefox no longer works as my Browser, eBay functions are just not responding, and it seems that my computer has ceased to operate as it used to.
I have emailed both Microsoft and eBay but this problem persists.
And we are not talking about 2005/2006 here.
This is happening right now, in April 2009.
Why has Dell not fixed this ancient problem?
Looking back over similar problems posted here I note that nobody seems to have had this problem with Windows Vista Home Premium, which is what I am running.
All of the attempted solutions seem to involve dismantling and reassembling a Dell computer!
Is this a usual Dell solution?
Most of what I read is way over my head — I am not a tech or a nerd — so I don’t know what most fellow sufferers are talking about.
What do I do?
I am in Dell hell.
Help!

I have a dell Dim 8400 with this iastore.sys problem. I can not boot windows. I have have tried the various bios methods here with no luck. Does anyone have any idea on how to make my computer boot so I can run the intel app and install the new file?
My Dell XPS 410 has never behaved consistently properly since I got it. I have called in various problems, bad sound, blue screens, etc. Finally the system would not boot at all. I was on the phone with Dell for a couple of hours and exentually they sent a new hard drive and video card. Installing these, we ran into the iastor.sys problem and finally that took us to your blog. Thank you so much.
I am apalled, though that Dell has known about this since November 2006 and I still had to have all this trouble. Have they never heard of patches.
I have a Dell Dimension E510 (Windows XP, media center, TV tuner) that I purchase in 09/06. It has been misbihaving for about a year (Amber light, shuts off by itslef and reboots on its own). Recently I got the blue screen error. After norrowing finishin a project under extreme preasure the computer finaly went out. Each time I turn it on it was just beeping and Windows XP never loaded. Of course my computer is way pass warranty so I took it to a locan computer shop. He found out one of my ram stiks was bad. So we get it on now, but it still turns off all by itlself. The tech sugested rebuilding the hard drives as he found some errors but I’m holding before I back up my system. I decided to research the matter myself and figure out what is the problem before rebuilding everything. This post is great at it discribe precisly the issues. After I backup my system I’ll try your suggestions. Thanks a lot and I’ll let you know later if this works permanently.
Guys what you are doing here is amazing, I couldn’t reformat my HDD to save my life, but it would always restart every time the OS boot loadbar would come up. Now it works perfect! Thank You sooooo much. -Dell Demension E510
I have been working on several Dell T3400 and HP 6730b systems with these same issues. I would get spontanious reboots and iaStor event log messages.
I have been able to get around this problem by simply changing the hard drive controller type to IDE from SATA in the BIOS. After, Windows loads the generic IDE/ATA drivers which completely bypass the faulty intel driver. After that, all is well. You can also try and download the latest driver from intel but i personally wouldn’t bother. I tried finding a suitable downlaod from dell but could never find one.
http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&ProductID=2101&DwnldID=17412&strOSs=All&OSFullName=All%20Operating%20Systems&lang=eng
And be sure to check your systems compatability before installing this driver!
After following the steps above and dowloading the driver the computer still shuts down all by itself. Although it now tells me that is backing my files in both hardrives and files are protected. First time the computer have given me such a message. I replace also the BIOS batterry and still the same problem. Now it has a beep when shuts down or trying to boot. I disconnected the I/O front panel as I found other web post stating it might be that penel but no result, it still shuts down. Some other furums indicated that the mother board could be bad. The last tech that looked at my computer stated that there were issues with the hard drive and it will need to be reformated. Any one has any idea what could it be?
Any thoughs will be appreciated.
Purchased a Dimension 9150 with the Dual Tv Tuner card, Raid etc etc.. Back in Sept. 2005. We are almost done payments on it, and only had the one year warranty. Now we seem to be having issues with it, and to no avail. I’ve called in my Computer Specialist friend who
came to the conclusion that one of my hardrives were corrupt, so purchased a new one to replace the one that went, and took the Raid off, and went with just the one drive, which went okay for about a minute, when I got a Blue Screen.. they come and go but get more frequent. Now I receive this new error, to which you refer, and I am now in Safe mode, because it is the only way I can get back into windows. My computer is now making funny beeping noises when I try to reboot, and sometimes it doesn’t even acknowledge that I have turned it on. Lights blink but no Dell Screen comes up. I am hoping that removing the TV tuner card will fix my error. I don’t know if I can call Dell about this because of my warranty, nor do I know how much it would cost to have the computer looked at. Such a pain!
hen i tried to install windows xp tablet edition on my GATEWAY TABLET PC
Setup did not find any hard disk drives installed in your computer.
Make sure any hard disk drives are powered on and properly connected to your computer, and that any disk-related hardware configuration is correct. This may involve running a manufacturer-supplied diagnostic or setup program.
Setup cannot continue. To quit setup, press F3.
is there a way i can load the drivers on a CD and boot it from there..because i know that u can put the drivers on a floppy and press F6 to load them..i tried using a usb floppy drive on my computer. files were cpied to floppy but i selected the intel Intel(R) 82801FBM I/O Controller Hub (ICH6M)driver but still i coudnt install operating system on my gateway cx2610 laptop.could any one help me?
Wow. This is amazing. I’m a Techie. And today my neighbor asked me to take a look at their PC which happens to be a DELL XPS 200/5150C. The problem matches what is described in this forum. To add to this… the PC runs very load and hot. Then the system experiences the BSOD. Has anyone else observed the Loudness and Heat ?

The Dell Dimension 9200 uses the Intel 965 chipset and has TWO SATA controllers, a 2 port and a 4 port. Each of these controllers supports ATA mode and RAID mode, except there are really three modes: ATA, RAID, and AHCI. Think of these SATA controllers as completely differnet PCI boards…because they are. When you change the drive mode in the BIOS you are changing controllers, same as unplugging one and plugging in another. The actual PCI IDs change on each controller afer the BIOS change and reboot and then a different driver is required. Of course, stock XP only has the driver for the ATA mode. If the chipset did not support RAID, everything would be simple as we could load support for the “new” controller one of 3 ways: 1) using F6 floppy 2) nlite slipstream, or 3) the post-OS-install “have disk” method. I’ve used all of those successfully on other ATA/AHCI non-RAID systems.
I’ve verified that the new RAID/AHCI PCI id for the primary controller is PCI\VEN_8086&DEV_2822&CC_0104 which is listed in the Dell and Intel driver .inf files. that leaves the following issues: What is the RAID/AHCI PCI ID for the four port controller? and for completeness, what are the PCI IDs for the 2 port and four port ATA controllers before the change? These are easy to find out..just install any other OS (Vista, Win7, Linux, VMware) and list the PCI IDs before and after the ATA/RAID BIOS change. Then comes the question we’ve all been asking…even with the correct driver (as determined by the PCI IDs) is loaded, why does XP crash? Does turning off the unused ports help? Does the existence or lack of existence of a RAID signature (from the Intel 965 ICH8R controller) change anything?
when in ATA/RAID autodetect the ICH8R presents 2 PCI devices a 2 port SATA IDE controller 8086:2825 and a 4 port SATA IDE controller 8086:2820. When the RAID mode is enables these two devices “disappear” and are replaced by the venerable 8086:2822 6 port RAID controller.

dell e520 just got the same bsodhas raid class drives in raid one running for months. tomorrow i’ll get my ultimate boot cd and try to repair it. this is my 3rd dead dell. my old compaqs are fin and my old home built asus’s are fine. from now on its my own atx standard mb’s with real bios.
all that mumbo jumbo aside, I succeeded in F6 floppy loading both the 8.5 and 8.9 version of the driver with the “RAID” mode on, on a single drive that tthe boot screen says “is controlled by the RAID BIOS”. Now on to nlite.
So, in summary:
F6 floppy install seems to work in RAID mode with 1, 2 or 3 disks in any combination (single, RAID 0, RAID 1) with the XP SP2 original install disk. Two caveats: 1) had to remove all partitions including the restore partition. 2) Install the chipset INF files and REBOOT before installing the iaStor driver version 8.9
I know this is a stupid labor intensive way to install an OS but it works and I cannot get nliteed version to install with the slipstreamed driver.
I bought an amd system this time. One of main reasion was fragile intel raid. I hope better stability this time.

I am having this problem with a Dell Precision 380 and R130119.EXE would not install because the system “does not meet the minimum requirements”. However, as per a post by somebody else above, it would install after changing the BIOS back to SATA AHCI setting.
The funny thing is that the problem has not ever occurred until yesterday to my knowledge, yet the PC is years old. Since yesterday it has already occurred three times. I’ve only just installed this fix so I can’t say whether it works yet.
hi i have the same problem (dell 9200) and have fixed it with the following
1-Download Intel drivers from dell site drivers for your computer
2 Move all the files to floppy disk
3-Boot your Windows XP CD and press F6 when it says to
4-install your windows now.
I hope it resolves itself for all
I have been getting this iastor.sys BSOD from when I bought my PC in jan 2009.but ignored it because it happened infrequently. now on the other hand i’ve been getting it 3 times a day. I am only posting because I believe that the problem isn’t with Dell products only, and was hoping for some help too. I am running a custom built desktop PC with an Asus P5Q + intel core2duo E8400 + Gainward ATI radeon 4850 + OCZ plat. DDR II 800 + extras. when I had my Soundblaster Audigy ZS plat. I got more BSOD’s, but still seems to continue even with that taken out.
Just got the iastor.sys, and blue screen, after rebooting the PC, can not go to safe mode or any other mode., then tried to repair the windows, by using the XP cd, but then got the blue screen with pci error message,I am running a total test of the system from utility, and tomorrow will try a couple of fixes suggested here to see if it works. first I wiil use the dell suggestion by 3/13/09 post. meanwhile if anyone had solved this some other easy way without opening the PC, and use of floppy please e mail me. I do not have floppy on mine which is a sell Dimension 9100 series. thanks
both instructions says to download a storage file, which I have on a USB card, but PC can not read it and I get blue screnn each time, now saying: AGE_FAULT_INNONPAGED_AREA, then giving the iastor error message.
PC will not boot to safe mode or any other mode so I can not install the file. any advise how to wrk around this?
I’ve found a fix for this on my Dell 390 Precision.
Install the latest inf files for your chipset – (infinst911autol.exe)
Install version 8.7 (IATA87ENU.exe) of the IMSM.
Edit registry
“HKLM\SYSTEM\CurrentControlSet\Services\iaStor\Parameters\Port0\LPMDSTATE”
“HKLM\SYSTEM\CurrentControlSet\Services\iaStor\Parameters\Port1\LPMDSTATE”
…
“HKLM\SYSTEM\CurrentControlSet\Services\iaStor\Parameters\Port5\LPMDSTATE”
values to be 0.
Reboot.
Then try copying a large file to your SATA connected drives and monitor the System Event Log.
I recommend not using IATA88ENU or IATA89ENU as for me they resulted in a soft disconnect of my drive & ntfs errors reporting corruption of the filesystem.
Thanks for making the effort to run and update this blog. By naming and shaming upou’ve saved me many hours of work. Now i just have to hope the newest driver works.

Thank you! Note that the BIOS settings were different on my Dimension E310 with RAID so I had to disable one of the two hard drives in order to access Windows and install the new driver.
Ironically, this is now 2010, and I got this message on a Lenovo ThinkPad T500 CTO2081. It has just happened, so I don’t know exactly what Lenovo will say/do about it. I have also just discovered that the university I work for, just lost their Lenovo “Certified Repair” status, due to, you guessed it, budget cuts. I find it interesting that this problem that has so plagued Dell systems 4 years ago, would find itself in a Lenovo system now… Hmmmmm Disappointed!

Have a Dell Dimension 9100 running XP Media Center.
Haven’t had major occurrences but always get the BSOD with a run of Malwarebytes (cannot ever finish a malwarebytes scan). Have had very occasional BSOD at random times, though rare. Can always boot right back up, so ignored it until the malwarebytes problem.
Have had random occasions of system shutting itself off, or getting stuck in a loop of shutting down and rebooting ywo or three times when I first turn it on.
I haven’t really lost anything, and it sounds like I’m lucky it hasn’t been worse. I don’t have a TV tuner card, but have a graphics accelerator. Was first told by someone that my conflict was with video drivers (Nvidia GeForce 6800…another piece of garbage right along with Dell). Updating drivers didn’t help, glad I found this forum.
Will try solution found through this site. Thanks for keeping it alive.
Thanks for this internet page,
I had the problem on a Dell Dimension 9150 due to an harddisk error that caused CHKDSK to produce the “iastor.sys, Windows XP blue screen error” each time I booted up using CHKDSK.
The Dell solution mentioned above at “11.07.06 / 4pm” solved the problem, so that CHKDSK later could fix the error without problems.
