yep, we're seeing it with our Optiplex 745s. We have the very small lunch-box size machines. It's caused by the hard-drive fan dying. Those little boxes have very constricted ventilation, and the hard drive is right next to those capacitors. When the cooling fan quits, the temp in the box sets off a "High-Temperature warning, Press F1 to continue" message on the monitor. Kind of like the red warning light on your car's dashboard. That "F1 to continue" is just too attractive for the end-user to resist. They're in a hurry to do whatever they're doing and don't want to bother reporting a problem to the systems staff. The user just presses F1-to-continue a couple of times, the hard drive hits critical temperature and bang go the capacitors. The only remedy at that point is to replace the motherboard, which we've had to do on about 8 machines so far. The best thing to do is to turn off the machine when you see that warning and replace the hard drive fan. That will fix the over-temp problem and prevent the capacitor bulge. However, in a lab of over 300 workstations, on 4 floors of my library, getting the word out to our 26,000+ student users is sometimes problematic. The Fall semester starts next week. Have mercy...
