To Start Things off my Computer Specifications. Specs: CPU: AMD Athlon(tm) 64 X2 Dual Core Processor 6000+ Motherboard: LP UT NF590 SLI Ram Speed, size and #sticks: DDR2, 4096 MBytes, 2x 2 Gig, Dual Channel GPU: 2x Geforce 8800 640mb in SLi PSU (do not leave this out): ABS Tagan BZ Series BZ900 ATX12V / EPS12V 900W OS: Microsoft Windows XP Home Edition Service Pack 2 (Build 2600) Problem: As i described in the title the BSODs are completely sporadic. I have found no pattern to when they occur other than the occasional BSOD during the boot process. This BSOD occurs during the Windows XP boot screen. History: I recently upgraded to the AMD 6000+, the second 8800 gts, and the PSU. The system was very stable up till a couple nights ago. No hardware or software changes were made to my knowledge. Additional Info: I had noticed that my Chipset fan had stopped spinning (It is very very close to the second 8800 gts), but with a couple taps it is back into action. I also have a monitoring tool that came with my MB to keep track of the temps / fan speeds. Everything checks out. All of my drivers and my BIOS are up to date, and no registry values have been modified. I will include the Minidump files i have. Thanks in advance for any help provided.
