I own an HP Pavilion m9636f workstation. Recently when I leave my workstation on unattended overnight I come back to it in the morning and there's a blank screen, no power, but I can hear the fan blowing. I get no response from the computer. I have to hit the power button for it to come back on and boot up.
I'm running Windows Vista 64bit, 8Gig Ram, NVIDIA GeForce 9300 GE (driver updated)
Any help or suggestions?
