My computer screen randomly goes black?

  • My computer runs fine anywhere from five to thirty minutes before the screen shuts off, saying "no signal". The computer still seems to be running (all fans are turning, the light around the "on" button is lit) however it does not seem to be responding. It is not in a power save mode, as the keyboard or mouse will not wake it up. I've reseated my graphics card, and it seems to be getting quite hot. Is there anything that I can do myself to fix it if it is the graphics card? I have tried using the computer with the case off.
