Pc not restarting

Nuclearbaggins · 7 Jun 2014 at 20:55

After having the whole house electrics trip out I have reset the breaker and everything seems fine except it seems my pc will not power up, it was on at the time when the electric tripped. But I was not using it at the time it was just idling, everything else in the house seems to be working fine. On closer inspection the motherboard power light is flashing along with the light on the antec water cooler and the two led's on the gpu.

I've tried disconnections the power and leaving it switched off but the same happens when I plug it all back in. There is no attempt in the fans to spin up and no other noise hdd etc when I attempt to power up. The mobo is a gigabyte z87x-oc and the power supply a corsair hx650w, I tried unplugging all the cables other than just the mobo 24pin with no change.

I'm not sure what to do next

Do you have a spare PSU to test with? Also worth trying is trying to start up with the bare essentials: No GPU, 1 stick of RAM, stock cooler etc. Hopefully nothing went pop

I don't have a spare psu, but I will try your other suggestions in the morning and let you know how I get on.

Test the power supply

It had actually come back to life this morning, but after half an hour the mains tripped again. So I tried the paper clip method and sure enough it didn't start up and the mains board tripped.

Edit: Gave it another shot using a different black ground cable because I wasn't convinced I could use any like he says on the video, because on the website it specifys the nearest one. So it has fired up but has gained a clicking sound now. Using the paper clip method.

Could it be that the psu is just temperamental, or is it likely to be something else.

The clicking has stopped once I plug the mobo back in and fire it up again.
