So i have had this pc for few years but today my pc turns on but my monitor goes into "no signal" i tried dhmi dvi or vga cables nothing... i got a new vga cable and still same issue. Can someone help me figure this out please? If i leave it couple of hours the monitor turns on when i boot but within a min or less goes black (sleep mode) saying no signal.
I reseated the ram and nothing helped. Boot device led is always on (red).
