Hello, my Dell has recently come up with a problem. I was using it for about 15 minutes and all of the sudden, it crashed. I wasnt in the room when it did but when I walked in, it was on and there was a black screen. I button powered it down and now when I turn it on, it shows a solid amber light. The cpu fan cranks up to full speed and the hard drive light and the 1 2 3 4 lights are solid amber too. I tried each stick of ram, took out my video card and tried a different power supply from a parted computer i had laying around and it still didnt do anything. It is a hot day today so could this be a overheating issue even though its been on longer on hotter days and it was fine?
