Changed RAM worked great took out to clean case put RAM back in have had no video since computer turns on and you can hear everything running but after about 2 minutes cuts itself off???can't hit start!no video???anybody???
Have you tried installing the origional RAM? When you took it apart to clean did you knock any cables loose? Did you take the appropriate anti-static precautions? There may be a chance that you fried the grpahics chip on the mobo, but this is an extreme scenario.
