I have a  emachines el1852g-52w that I forgot to register and now cant find the receipt so cant register it for the warranty. I was told what might be wrong is the video card. The tower turns on and about 10% of the time, it will show up on the screen, the other 90% of the time it will not. It will go into sleep mode ( I have turned it off since thinking that was the problem) and I can't "wake" it. but it is just because it is not showing on the screen. Is this a video card or possibly something else? I have changed power supply cords, moniters, and searched everywhere I could think of for another answer. thank you~

The el1852g contains an Intel® Graphics Media Accelerator X4500.  This is located on the mainboard.
