I have an MSI K7T266 Pro2 Ver: 2.0.
A couple of months ago, the power supply died on this system. At that time I noticed that fully half of the caps on this board were either swollen or vented. When I asked at the shop where I got the new PS, they said that event though the board still POSTed on a good PS, it would probably destroy the new PS within a few weeks.
I replaced both the PS and MB (A Foxconn they had on clearance), reusing all the other components. The system has been running rock-steady since then.
This system had been running for nearly three years, but I'd had stability problems for at least two of those. It had a tendency to freeze when I would plug in USB devices to the front-panel USB 2.0 connectors.
13 of 24 capacitors appear to have failed--bulging and/or vented. These caps are all either Tayeh (Wikipedia lists this as a company that doesn't appear to exist) or Lelon. The Lelons are 1000uF 6.3v 8mm cans and all appear to have failed, many venting. The Tayeh's are 1500uF 6.3v 10mm cans and appear to have bulged slightly.
The others that don't appear to have failed are 10mm cans either 1500uF 16v or 2200uF 6.3v. Their brand name may be KZG. They are dark brown with grey stripes and lettering.
If I recap, I would replace all of them, even those that appear to have not failed.
My main questions are:
1) Is it likely that the bad caps were the cause of the power supply dying?
2) Is it likely the freezes when plugging in USB devices were due to the bad caps? There are two of the 1000uF caps right at the USB 2.0 headers, both vented.
3) If I recap, is it likely this MB will be stable? I'm thinking of upgrading an old (PII) system with a new PS and this MB, but would need to add a new CPU and RAM as well.

Then I glued it back together and it still works. You have to be careful not to bend the board too much by hitting it with the sucker when it recoils. My instructions:
