Hi guys, girlfriend is having problems with her pc. Specs intel 3.2ghz 1 gig ddr 2 667mhz 1 x radeon1650 pro 512mb pci-e c 80 gig hard drive 17 inch monitor problem - random black screen while gaming/surfing crashes/error message/blue screens of death - none memtest ran overnight - no errors found. All drivers are up to date and running the latest versions. Nothing on the pc is over clocked. Using asus pc probe, volts seem to be reasonably stable, staying at or just above where they should be. Cpu temps are seem fine, as do graphic card temps. Legal copy of windows, all up to date. Pc never crashes, or games with any specific errors, just the black screen problem a few times a day. Help appreciated, if you need anymore info just ask.
