I've a Dell Dimension 3.0 with 1024ram and a 9800PRO graphics card. I run NOD32 anti-virus and a firewall. A few nights ago I'd left my computer running a download. (this may be in the wrong forum, but I'm not sure if its virus related or hardware.) I turned my machine of halfway through the night, and it had some form of error message displayed (I was sleeping on my feet and this didn't register with me untill the next morning.) Now when I start my computer and XP has finished loading, at the exact point where the screen would go blank for a second before desktop appears, my monitor goes into power-saving mode. Windows continues to load because I can hear it's little tune through the speakers but the monitor remains fast asleep. Safe mode just does the same. When I start it in safe mode with prompt it scrolls through a list of files untill it gets to win32/...(some random file stuff)/agp440.sys and then it hangs.
I realise this is all very noobish, but I'm very much a novice at this.
