I had to steal the PS from this computer for another more critical one whose PS up and died. Did some research and found that the 500W Antec Basiq 500 was alleged to be a good one for being modestly priced, so I bought one (the original PS was also an Antec, 350W, and it ran flawlessly for all those years). the trouble did appear a while afterthat, so it could be something weird about the PS. I don't have a 'scope to view the noise levels of the output, but at least the voltages all look good on my DVM while under "normal" load. the video card does have a fan, I'll have to look at it again--last time I checked it was running fine. there are actually six fans in the computer, and all were fine at last check. little dirt in it--there's a filter on the intake in front (with a 120mm intake fan) that I cleaned while I had it apart to steal its PS, and mopped up what other loose filth I could find. mostly, the collection of cat fur on the input filter nicely blocked smaller bits of dust from entering. :) It usually gets opened up and the fur cleaned out twice a year, more or less. > > > > > Thanks! > > > > Fred > > -- > Robert Heller -- 978-544-6933 > Deepwoods Software -- Download the Model Railroad System > http://www.deepsoft.com/ -- Binaries for Linux and MS-Windows > heller at deepsoft.com -- http://www.deepsoft.com/ModelRailroadSystem/ > > _______________________________________________ > CentOS mailing list > CentOS at centos.org > http://lists.centos.org/mailman/listinfo/centos -- ---- Fred Smith -- fredex at fcshome.stoneham.ma.us ----------------------------- But God demonstrates his own love for us in this: While we were still sinners, Christ died for us. ------------------------------- Romans 5:8 (niv) ------------------------------
