I have been baffled by PSU problems. I bought a new Abit NF7-S board in Jan. It posted a couple of times and then it would not do anything( CPU fan spun about 1.5 seconds). Thinking it was a power supply problem, I bought a new Antec 430 and all was well. I kept the old PSU, even though I assumed it was bad.
Fast forward to Aug. A buddy of mine has a computer that quits working. He takes it to a Mom and Pop Shop and they sell him a new PSU, but the rig still won't post. He gives it to me and I check all the usual suspects (did not check the PSU!) and figure it is the motherboard. He decides to upgrade, I order the parts (XP1800+, Shuttle AK38) and put it together. Nothing! CPU fan spins about 1.5 seconds. I tried everything. Finally, I try a new in box PSU (400W) and bam works like a charm. He returns the old power supply he just bought, they check it out and say it was fine?? Now in Oct. his box goes down again!! I try everything else! Finally I try the original PSU I replaced in Jan. and the dadgummed thing worked perfectly!
Will a PSU just not function any longer in a certain board, but still work fine in others?
