most Power supplies that come with a case arent worth spit. ( antec being an exception) if you have acess to another power supply I would suggest you try it and see if that is the problem.

If you've been having power outages lately, it might be dead. Sudden power outages, surges, spikes, etc... can kill a PSU.
