Hi guys, here's my problem... I have the pc with the following spec: AMD Athlon™ 64 FX-53 Brushed Aluminium ATX Midi Tower +550W PSU - Black ASUS A8N32-SLI Deluxe PCI-Express Mainboard - ATX 2048MB DDR400 Memory - PC3200 (2x1024) 300GB Serial ATA Hard Drive with 16MB Buffer SONY 16x Dual Layer DVD-Re-Writable +R/-R/RW SONY 16x Dual Layer DVD-Re-Writable +R/-R/RW 512MB DDR2 nVIDIA GeForce 7300GS - TV out- DVI - PCI X (256Mb SMA) Creative Labs Sound Blaster Audigy 4 Sound Card Internal 15-in-1 Memory Card Reader It originally worked fine, Then, about 3 months ago, it started playing up, BSOD, page fault in non paged area errors etc... I rebuilt the pc (formatted, and re-install windows) several times, no help. i then installed windows vista ultimate, same problems i've attached 3 dump files, i've used windbg to have a look, but really cant tell if anythings wrong. i've not changed any of the hardware since i got the pc.
