sudden big problems with HTPC

sudden big problems with PC

suddenly the pc started with "bad bios checksum" so I loaded default and off we go. stops at "windows did not load properly" so I press any key and by pressing pause break key I see many lines with this as an example:
multi(0)disk(0)rdisk(0)partition(1)\windows\system32\ntoskrn.exe

I then get a BSOD with an "IRQ not less or equal" and then a reboot
is this a completely screwed windows or a hardware conflict that didnt exist before?

system:
Asus A8R32-MVP
AMD opty 146
2gb RAM (corsair I think)
Nvidia 7800GT
WinXP media edition.

thanks for looking.

now decided to reinstall winxp mce. removed wireless network card and sound card and still getting BSOD. If I attempt to install on either of the hdd's I still get a BSOD.
which leaves the cpu the video card and the RAM. can any of these 3 cause IRQ conflicts?

It sounds like dodgy ram. Try booting with one stick at a time.

I removed 1 stick and it booted fine. Replaced the known good stick with the dodgy one...no boot, just errors. Ran with both in dual mode...no boot, so it must be that 1 stick has gone phut.
will try memtest with usb floppy just to make sure before requesting RMA.

cheers

Maybe Nacho just likes fire

Do you need more then 512mb RAM for a HTPC? See how it runs with just the one stick.

yes it boots fine with just the 1 stick, its just when both are in that it dies. Ive previously used this RAM pair in another system (same mobo and cpu) and they performed OK

i had the same prob and the culprit was the mismatched xms ram

did yours work OK at first or were they bad from the start?
