A bunch of PC manufacturers are being hit with bad capacitors. (If you slept through high school electronics, capacitors are used to temporarily store electrical charge and regulate voltage — old timers sometimes call them condensers).
CNET has a good picture of the problem:
You can see the swollen caps in the back. These things swell and then leak a kind of yellow goo which crusts over, utlimately causing video problems and intermittent system failures.
Dell has this problem on some Optiplex workstations (incidentally, the very workstation I have in my office). But they aren’t the only ones. We’re talking about HP, Apple and apparently others have this issue.
Unknown is how widespread the problem is.
