My computer refuses to start up. When powered on, the monitor light flashes (as though it is on but receiving no signal) and the num lock, caps lock lights flash. There is no Beep Sound. The cpu fan is working, and i have tried with a different hard drive and it still does this. So its not the CPU or the Hard drive. Ive tried unplugging the cd and fdd but have the same problem. I remove RAM and VGA too. But there is no any beep sounds also. Im beyond lost. Does anybody know how I can fix this?
