Most Dells come with a utility you can launch when the PC boots. Restart your PC and see if you see something about a diagnostics utility or something to that effect. If not try popping in the Dell cd that came with your pc and reboot again....
When you run it run all the scans and write down the error codes the scan gives you. Then you can call Dell and give them the error codes and they'll tell you exactly what the problem is and the best way to go about fixing it. If no error codes then...
What you might consider is that it's overheating. Make sure the vents are getting enough air.
