Msi 760GM-E51 MS-7596 thought was dead, disconnect cmos battery now ok

Msi 760GM-E51 MS-7596 has been a good board.
My 650 watt PSU quit with an odd noise, but might have been speakers.
So I thought just get new PSU. Using new PSU board refused to start or do anything.
Thought it was dead took it out of case. Saw and smelled nothing wrong.
A few days later, after ordering another MB, decided to remove cmos battery, put it back in after a few minutes.

Suddenly board comes to life and boots. So the failed PSU did something to something that prevented the board from starting up. Board was so dead pushing power button did nothing, no lights on board, no fans.

I have been using the PC since then for a week with no problems at all.
Must be a pretty good board to survive ok.

One possible explanation: the connectors that touched the + and - of the CMOS battery were dirty; by removing and reinserting the battery, you scraped and therefore cleaned the contacts.

Another possibility: by removing all power from the motherboard for a bit of time (including the CMOS battery), you totally reset all volatile memory on the motherboard, thereby clearing up the problem. I think this is the most likely explanation.

It's possible that in the bios something was set wrong removing battery would set it back to default
