Eventually Windows would not repair. While looking in the BIOS I noticed the screen go wonky with lots of wrong characters appearing as it froze. I've never had a PC freeze while looking at the BIOS. It's gone now. It switches on, the CPU fan spins, the CDROM LED twinks a little but the familiar front panel LED no longer blinks and there's no startup bleep. This is a Gigabyte 78LMT-USB3 v4.1e mobo. It has integrated graphics. Apart from saying it's a mobo fault. What else can I say?

I have not tried to swap out any components yet.  That PSU is the best and newest I have but I may buy a new PSU today.

I have more detail. The system partly recovered. It passes POST now. It behaves as if it has an intermittent fault. The fault strikes after about 5 minutes or more. The effect is to freeze the system.
