[QUOTE=cyber_x,Mar 4 2005, 10:31 AM] If you haven't added any new hardware lately, then it could be a dying power supply.

Before anything else though, open your computer case and spray everything with a can of pressurized air.

 

Thanks for the updated responses. Your problem is puzzling indeed. Since it "freezes" on the first power-up, it is most likely not a heat issue. Freezes like that can be caused by a thousand different things, ranging from hardware to software. But because you have recently replaced the power-supply, I'd start there because it is the most likely candidate. Try putting the original power-supply back in and see if the crashes still happen. You may also think about any new software that you have installed recently. Good luck.

 

what brand was the higher wattage power supply?
