My computer will boot up with no problem, then after using it for a short period of time, my screen goes black and it says "no signal." It appears that the computer continues to run during this time. If I reboot, the screen is visible for a short period of time, then again goes black.
The only info I have on the card is that it is an NVIDIA Geforce 3D(?) 64mb. I apologize that I don't have more info handy as I have not had any problems with it since I built it in 2002.
BTW, my electricity goes off every time the wind blows and has repeatedly rebooted my computer for me.
I believe that the card has gone bad and needs replaced, but would appreciate your thoughts.
