I was overclocking with my new motherboard last night, and I hit a wall at 3.5ghz, So I decided to raise the voltage to 1.5v and go to my goal of 3.8. Well when i did this, the pc booted up fine, got into windows, ran for about 5 minutes, just enough time for me to check the temperatures (they were around 130f, well within limits for a prescott) and then all of a sudden my pc just turns off. Now it won't turn back on. Do you guys think its a power supply problem? I've been running a not so great Enlight 300w.
