What is wrong with my computer when the monitor shut down but the computer is still on. My computer is an HP Media Center PCm 1095c Pentium 4. I already clean the inside.
Thank you guys for replying.. I guess my question is the picture in the monitor goes out but the power to the computer and monitor is still on. I solve the problem by looking at the video card. The video card fan is not working which indicate video card is overheating that is the reason I see picture for a while and then disappear. I replaced the video card and it solved the problem. A $23 item from Ebay if you could find one. Make sure that if you are buying a video /graphic card that edge connector is the same as yours. Mine is a PCI Express.
