Alright, as I posted in the /dqn/ "ITT we solve the question above us" thread earlier:
Alright, so I put this new PC together, and it keeps crashing during WinXP setup. I've updated the BIOS, exchanged the CD/DVD drive, low-level formatted the harddrive twice and taken out all nonessential hardware. Yet it still bluescreens during XP setup.

I might also add that I tried three different pirated WinXP Professional CDs, one with SP1, the other two with SP2 (one of them a modded unattended setup one). All of them crashed and bluescreened at a random point during setup (the furthest I ever got was on SP1, a couple minutes after accepting the default network settings). The computer also behaves a bit strangely in other ways. For one thing, it refuses to boot from floppy, always giving me an I/O error when I try (yes, I have tried different floppies and different drives). I spent hours trying to find a way to get a DOS boot CD because the BIOS update needed DOS. For another thing, even booting Knoppix it occasionally hung for no apparent reason.

So yes, I'm thinking of sending the machine in to this computer mag I subscribe to. They're running a "bug of the month" feature where people send in PCs with particularly tricky problems and they write up their solution. Any other suggestions? Specs of my PC are:

Mainboard: Asus A8N32-SLI Deluxe (got slightly used off ebay, BIOS updated to version 1205)
CPU: AMD Athlon 64 X2 4400+ (bought new)
Graphics card: Axle Geforce 7900 GT (bought new)
RAM: 2*1024 MB (noname,removed from a newly bought budget PC)
DVD burner: LG (don't have the model number, came with the same budget PC)
HDD: Maxtor, 300 GB, S-ATA (also from budget PC, partitioned using PartitionMagic into one 10 GB, one 90 GB and two 100 GB partitions, all FAT32)
