Blue Screen Prevents Startup!

Hey everybody, my first post here and unfortunately in need of some urgent help please.

Some background info to my problems:

At some time in the past 2-3 weeks my PC was infected with spyware/malware/viruses (no idea) which caused massive slowdown and questionable programs/processes to be installed on it. I’ve used your extremely useful guides in the past with success whenever malware reared its ugly head.

However this time I couldn’t shake the malware (scanners and removers/internet browsers keep crashing). I ran “msconfig” to enable the start up in safe mode option but from that point onwards, every time I attempt to start my PC I encounter the “Blue Screen of Death” before I can logon. Every start up option in the Windows Advanced Options Menu (Safe Mode through to Debugging Mode) results blue screen error.

When starting in the various safe modes, the screen fills one by one a list of lines beginning with:

multi(0)disk(0)rdisk(0)partition(1)\WINDOWS\system32\ (zeros have dots in the middle)

Ending with:

multi(0)disk(0)rdisk(0)partition(1)\WINDOWS\system32\DRIVERS\iomdisk.sys

Then bang! Blue Screen. The text begins with “A problem has been detected and windows has been shut down to prevent damage to your computer.” It also states if this is this first time restart the computer, if it appears again check for viruses and remove newly installed hard drives. Check HD for corruption, run CHKDSK /F etc. The crucial technical information is:

*** STOP: 0x0000007B (0xF9E49640, 0xC0000034, 0x00000000, 0x00000000)

All I know about my system is that it is a Dell PC with a Pentium 4 processor, originally running Windows ME then was updated to XP Professional.

That’s all the information I think is relevant, please ask me for anymore should you require it. Hopefully we can get past this problem and then deal with the malware together.

(I’m using my sisters laptop at the moment.)
