Windows 7 Blue Screen of Death - IRQL - iastor.sys

Partzfx · Jan 16, 2011

I was working in firefox and the screen went wild. The computer went wild and started shutting down. I get this that error. Sometimes it will allow me to start it with safe mode with command prompt or with networking. Here is the link to my minidump file located in office.live
Link Removed due to 404 Error

Does anyone have any idea what I can do?

Thanks for the help

Rick

My computer is

Dell XPS 1645
8 gig RAM
i7
ATI 1gb video card

How to get this? No internet on the computer. I can copy file to the computer and that is it.

Disable Ricoh Memorystick Controller in windows device manager while in safe mode.

To restore normal boot:

1. Try Last Good Known configuration
2. Startup Repair Options Link Removed
(Download Windows 7 System Recovery Discs )

3. On the Startup Repair from Command Prompt:
a) sfc /scannow
b) chkdsk /f

4. If you have a backup image you can restore from it
5. System reinstall would be your last option

If nothing works including the reinstall, test memory and the hard drive:

Memtest86+ - Advanced Memory Diagnostic Tool

Thanks cybercore for the link. Excellent guide, very comprehensive. Read your reference pages and their links to addition pages 51 and 52, cannot figure out how to update the sigs on another computer? Unless maybe if you had the full retail version installed on another computer and then was able to build your own rescue disk from there? Is that what we're talking about? Pages 51 and 52 are both headed by "You must have an Internet connection to update." (in red).

Hi all,
I had the same issues with BSOD/iastor.sys and couldn't boot most times. Spent a few days trying to rollback, repair, restore, even rebuild the MBR, but nothing worked. It turned out to be a nasty rootkit infection. Had to use kapersky's tdsskiller.exe to kill it. I was able to boot into safemode with command prompt and run it (though 9 times out of ten safe mode would BSOD). Once I got it to run it took about 30 seconds to find it and kill it. See these threads and sites for more info:

Good luck!

Thank you for sharing. Yes, viruses can cause BSOD's too - that's why for any stop error MSDN recommends virus scan:

msdn]The following actions might prevent an error like this from happening again: - Download and install updates and device drivers for your computer from Windows Update. - [B]Scan your computer for computer viruses.[/B] - Check your hard disk for errors.[/QUOTE] [QUOTE=cybercore said:
You can also update it on another PC. Pages 30-31 of this official pdf tutorial http://support.kaspersky.com/downloads/guides/kasp10.0_rescuedisk_en.pdf.

Yes, this is to update the boot .iso on another PC running Kaspersky.

Actually when you download and burn the ISO, when you boot to the CD, it will autoconfig the network and from the interface you will have an option to update the current signatures to the most recent available. Excellent tool has recently saved my butt, actually my daughters butt, it was her laptop.

I would try this way first - easier and faster.
