I've recently had a problem with my pc (built myself) it was fine for 18 months then a couple of things happened and I lost my motherboard, processor and PSU in the process. Thats not the problem. The problem is i've just replaced them with a Biostar M7NCD motherboard, Athlon XP 2600+ processor and a Q-Tec 400W dual fan gold PSU. It's the PSU that I think is the problem and I wanted a second opinion.
When I was re-installing (fresh install on formatted HD) Win XP Pro, it would get to a point then the PC would cut out altogether. The only way to restart was to remove the power cord, give it a few seconds, then reinsert it (first clue that its the PSU) I solved this by dropping the fsb down from the proper 333 MHz (166) to 266 MHz (133), so lowering the voltage. (*yawn* I know this is long winded but the main problem is coming now) Now I'm running the 1.9 GHz processor at 1.6 GHz, but when I load the processor with even the most basic of tasks (converting WAV -> MP3 for instance) the power cut occurs again. Does anyone agree it's the PSU or is there something else i'm missing?
