I'm working on a Dell XPS M1530 laptop that seems to be having a lot of hardware issues. The laptop originally had Vista Home Edition 32 bit but now it is running XP home edition 32 bit. The main issue with with this laptop right now is that it will not power on at all. When I push the power button, the media buttons above the keyboard light up momentarily and then turn off. The screen does not come on. The cpu fan is not running at all (I noticed this by visually inspecting it), and the laptop does not seem to be running. The only thing that does run is the hard drive (you can hear it running). Prior to this issue with the laptop not powering on at all, the screen was having issues. The screen had gray parts near the bottom where it was slightly dimmer (however the rest of the screen was still working fine). Also, whenever the computer was doing something more graphically intense, like playing a game, the computer would crash. What could possibly be wrong with this laptop?
