GA-H55N-USB + Core i5-760 shuts-off after 10/15 min

[stef1205]

Hello,

I assembled already about 4 GA-H55N-USB based systems but one of them all of a sudden stated shutting-off randomly 10 min after boot ( even under bios only ).

This system worked fine for about 2 month before starting to exhibit this behavior.

I first thought it was the PSU so upgraded it ( 600W ) but same issue still remains. Then swap the CPU still same. Then swap the RAM no change.

I tested very dumb down fail-safe min speed bios settings no change either.

My only thought is the mother-board. Is that a known issue ?

When the computer goes down it can't be started again for about 10 min after power cable has been disconnected.

Then it starts again but always goes down after 15 min regardless if I boot into the OS or stop at bios stage.

Thanks for any advice,

Hi and welcome.

It would sound most likely like a heat or power issue. Double check all your heatsinks and make sure that they are all firmly fixed and the fans working properly. Remove and refit your power cables to the motherboard...that is the 24 pin and the 8 pin. It is possible that there is a fault with either the CPU or the motherboard of course.

You haven't got a "Green" hard drive as your boot drive have you ?

Can you list your hardware so that we have a better idea of what you are running.
