Computer Shutdown Issues

[BRP17]

Ever since I had my power supply replaced, my shutdown has gone haywire.
Almost every time I click shutdown, it restarts. Once Windows {7} opens
I can the click shut down again, and it does.
Upon occasion, I can click restart and it will shut down. But that's not consistent.

Very odd. Does your BIOS allow you to choose your shutdown states? I would check there first.

I'm in BIOS now. Not all that versed on it.
I don't see anything that gives me that option.
I'm in ASUS EFI Advanced BIOS right now.

Reload defaults and save.

Note down what the boot settings are and the SATA modes too.
