Thread: No signal

My computer keeps going off and saying no signal, sometimes it will go off every few seconds, someday it won't go off at all?? Please give me help me to solve this problem.

The system shutdown or restart it self? The monitor says no signal? Do u have graphic card installed?

So every time you push on button you hear a short beep? there's a difference between restart and shutdown
restart= goes off then start itself
shutdown=goes off is your system shutdown or restart itself? I suspect bad ram.
