This morning the wife reported her computer was rebooting itself automatically. By the time I got to it, it was in BIOS saying something about the CPU not performing properly. I made sure it was at default frequency (1666 MHz) and rebooted. Sometimes I got into Windows without rebooting, sometimes not. CPU temp was about 65C, chassis 39C. No alarms. I honestly don't know what it normally has been running at. I opened things up and played around a bit and noticed that 1 of the 2 fans on the PSU, the interior "intake" fan, was not turning at all. I checked everything out some more (chassis fans, etc) and restarted. It ran pretty well for a while, rebooted once, and then ran perfectly fine (as my MP3 server) for the rest of the day. Tonight after work I pulled everything out to investigate. I could not get the power plug to easily pull out of the motherboard, and upon further inspection noticed some dark discoloring. I finally got it to lift slightly, and could see that a few pins looked rusted or burnt. I sprayed a tiny bit of wd40 and got the adapter loose. Have a look see. Something definitely spiked - any/all the pins that are hot (4 red wires) appear burnt. Obviously between that and the dead fan, it's time to scrap this PSU. My question is what I should do with the mobo, and what should I expect from it now? The machine ran fine all day (maybe several?) like this - so as far as I know all components are totally fine. Is it possible to replace the white plastic outlet on the mobo (and clean the pins at the same time)? Or are those affected pins just a time-bomb no matter what? This is an old rig that's been together in this config (except for hard drive upgrades) since 10/2003. Asus A7V8X, Athlon XP 2000+, Antec 350SL, ThermalTake HSF, etc. It was behind a Powercom UPS unit and one APC power strip. Collateral question-- After being away for the weekend about a month ago, I came home to a shot AC/DC adapter on my D-Link gigabit switch. About a week and a half ago my next-door-neighbor's TV would not turn on any more after some noticeable/strange power surges. Is there something I should start monitoring in respect to our power situation?
