Computer shutting down
No 2 son has a Gigabyte mobo in his desktop PC. It is shutting itself down at exactly 30 minutes. First step was to replace the PSU - same.
It matters not whether we leave it on the Bios setup or boot into Win7, exactly 30 minutes each time. All temperatures are normal, fans ok. This has me beat!
The internet has several similar cases with other mobos but no solutions. I am not aware of any BIOS or mobo setting that will actually shut down at a fixed time - is there one?
