I built a computer about a year back that has had stability issues since its creation. I'm assuming its hardware because reinstalling, updating drivers, and scandisking do nothing to rid me of the problem. The trouble is I can't narrow it down to any particular piece..

I get BSODs on win32k.sys and notskrnl.exe most notably, and it crashes on everything from opening new file in Photoshop to browsing the internet. Each of those error messages indicate problems in either MotherBoards, Processors, RAM, HDDs, NIC cards, SoundCards, or VIDcards.. nice and narrow, right?

Anyways, here's my hardware:
ASUS A7M266-D Dual processor motherboard
Dual 1.6 Ghz AMD processors
Geforce 4 128 MB by nVidia I believe
SoundBlaster2
Linksys10/100 NIC
Generic 512 DDR ram
Maxtor 80GB HDD and WesternDigital 80GB HDD

Any ideas??
