Windows 0x0000007B error

Hey guys

Was just browing on the net Saturday and all of a sudden my pc bombed. Upon reboot I got a BSOD and it mentioned something about "IRQ LESS THAN OR EQUAL" so Installed XP onto another drive and ran a virus scan, chkdsk etc on it.
Anyway removed lots of virsuses with Avast using a bootup scan, now the BSOD said "STOP 0x000007B" on C:
What is strange is that I have no option to use windows repair from bootup. Ive definately used windows repair before, also recovery console is missing.
I booted into D and installed windows recovery console and tried using various commands such a fixmbr and all those others to fix the bootup. Anyway its been ages now and I'm at a loss what to do next. I think that if I could somehow get windows repair on the installation on C: It would fix it but don't know of any way to access it.

Has anyone encountered a similar problem, what could cause the boot from Cd not to see previousley installed versions of windows and not to offer a repair or console?

Many thanks

I have found in the past this error relates to memory problems. Either grab a copy of memtest86+ to test your memory or remove one stick of memory at a time and test.

Check that your memory is running at the correct voltage and timings.

Assuming your drive is SATA and have the option in the BIOS, try changing the SATA mode from AHCI to ATA/IDE or vice-versa.

Isn't this relating to inaccessbile boot device? Could be the mbr. Can you use fixmbr ?

Thanks for all the replies, I always try to fix things like this before just re-installing.

Admiral Huddy, I doubt it is the RAM as the symptoms of windows not being to do a repair where it previousley had, also new RAM recently installed and the computer is running fine on another partition.

Dappy, I'll give that a go but not seen any options for it in Bios though, why would it have gone wrong all of a sudden though?

Deathwish, I've done a fixmbr and pretty much everything possible in the recovery console, its shame I can't run repair from console.
