, Please help Ive got a computer of mine. he wants me to fix it. My friend was just surffing on the net and when he finished as usual he turned off the pc. Next morning he tried to turn it on but there was no disply even though there was no problem with it the night before.The computer starts fine the picture will appear on monitor for 2sec and the screen will go black. The computer still works fine though. Ive checked the ram memory and graphics card also replaced them but it did not help. The computer beeps once when it starts which means that system boot successfully. Ive tried swapping the dvi cable but it didnt help. Tried different monitors but still had no luck.

Graphics: Matrox Parhelia APVe
