I'm having a day where I feel really stoopid. I've been going nuts trying to figure out problems with three Optiplex GX270s, all with intermittent weirdness type problems - shutdowns, time and date issues, lockups. All passed the nearly useless little Dell diagnostics routines, all worked just fine a lot of the time.
*Finally* opened the cases this afternoon, and all three have domed capacitors on the motherboard. Doh! I should have checked that *ages* ago. *slaps forehead*
All are out of warranty, too. Fun. They would have been out of warranty even if I'd figured this out a few weeks ago when the problems started, but even so...makes me kinda mad at myself.
I got to spend my whole morning with someone staring over my shoulder as I debugged. I hate, hate, hate that. And it was literally all morning. And I had meant to come in and get to work on the other task I was assigned weeks ago and haven't done... got around to that at 1:30, at 2 got dragged off to a high-level design meeting. Oh well.
