Power Surge- Damage to Motherboard?

Built a new system three weeks ago. Everything was great for awhile.

Got BSOD a week ago, said "Memory Fault" caused the crash. Restarted it and never happened again.

Last night it shut down and said something like, "Your computer shut down to protect itself due to a power surge". The computer no longer shuts down. It will restart though. (Both through windows)

I have a surge protector. My 24 pin power connection is loose because it doesn't "click" in. It doesn't go far enough into the connector to lock in and the computer has shut off 2 or 3 times while I was fiddling inside the case when I bumped the power connection.

Could I have damaged the motherboard? Memory? Maybe corrupted the SSD?


In use everything seems to be running as normal. When I click on shutdown, it says "Shutting down" then the monitor turns off. All 7 fans and lights in my computer are still on though! What should I do?

Thanks for your help!

It is possible that a short in the 24pin happened while it was loose.

If you have only had it for about 3 weeks I would suggest trying to get an RMA on the board. Also, I would suggest getting a new PSU that clips in correctly.

The power connector appeared to be slightly loose when this happened. Maybe over a week fan vibrations made it come out far enough.

That is very possible.

I have also just discovered it does not go to sleep either. Is there anyway to diagnose problems with the motherboard?

Not unless there is a error code on the board.

You can try updating the BIOS and see if that clears anything out.

BIOS is now updated. No changes.

Looks like it might be physically damaged. Try to get an RMA replacement.
