I'm stumped as to what is wrong with my computer. Out of nowhere, it started doing this:
The output on screen starts shaking (the entire desktop), then the monitor starts turning black, then coming back on, and on and off quickly a few times, and then finally it just goes black and reads "no signal" (as if the computer was off).
If I turn the computer off for some time, and then start it back up, it works for a while and then the problem begins again.
Suspecting an overheating issue, I checked the video card fan and it was fine. Therefore, I swapped video cards in case the video card was faulty, and, no difference.
And that is where I stand now. If I restart the computer after the screen finally flickers off and stays off, nothing comes on screen upon startup.
This makes me think it's clearly a hardware problem/heating problem, so I'm wondering if it is the motherboard, since the video card doesnt appear to be the problem.
Any ideas?? Your suggestions are appreciated.
