New Mobo necessary?

[me(who else?)]

I recently was charged with fixing a moderately expensive computer., I have tried testing every component and replaced the CPU, but I can't find the problem. My comclusion is that the cheap, no-name PSU killed the Mobo and damaged the CPU (It was BSODing like mad before). The person who I'm fixing it for told me that it was shutting down seemingly randomly. A new CPU patched the problem, but it started getting more and more frequent until *Bang* , it just died. The 2600+ is still good, but the 2200 that was there is toast and everything but the PSU and mobo seem to work fine.

I just need a second opinion...

You'll need a new PSU anyway, so why don't you start with that?
If that doesn't solve it, get another mobo of the exact same brand and model, that way you don't have to reinstall windows.

I already tested the mobo with both the old and a new PSU and it seemed that the mobo was bad (ie. with the 2600+, a new PSU, I already knew that the RAM was good, already tested the video card).
