Hi guys, a PC I built after buying the parts on here back in 2012 has decided not to boot for me, it was having issues with Grub (I had Ubuntu dual boot), then it booted up today with a BIOS screen I'd not seen before, before shutting off.

Turning it on, PSU spins up, CPU spins up for a few seconds then it turns off - repeat in a cycle.

I took the stock cooler off, cleaned off the paste and applied new.

I've unplugged everything, just down to the PSU with the ATX cord for the board and the one for the CPU plugged in and it's still doing the same.

Think the PSU has gone? It's a 550W OCZ one.
 
Here are the specs

Gigabyte Z77X-D3H Intel Z77 (Socket 1155) DDR3 Motherboard
Intel Core i5-3570K 3.40GHz (Ivybridge) Socket LGA1155
OCZ ZT 550W '80 Plus Bronze' Modular Power Supply
Patriot Viper Xtreme 8GB (2x4GB) DDR3 PC3-12800C8 1600MHz Dual Channel
Samsung 128GB SSD 830

I'll check the voltages Tealc, I'm getting about 10 seconds so should be time enough.

I have another PSU in my main gaming machine, just a ballache to take it all out, but might have to do that to see if that is the issue.
 
Thanks for the help guys, tried another power supply yesterday and it did exactly the same thing.

The Bios did flash up something I'd never seen before just before it all went wonk, it flashed up too quick for me to see.

So clearing the BIOS? I just take the battery out for a few minutes? Or get a new one and try that?

fenchu - getting a new chip, I wouldn't know where to start with that. Is it something I can fit myself?

Thanks again for all the help.
 
Thanks Tealc.

So I tried cycling the power button, leaving to stand, clearing the BIOS (I found a jumper to do this) and then gave it another go.

Power supply is now staying on, cpu fan is staying on, but nothing showing on the screen.
 
Thanks Gaz Mc, that quick almost blank BIOS screen looks familiar, I had it once before all this started happening.

After using the jumper to reset the CMOS again, I managed to get it to go into BIOS once, with everything reset. I thought I was back in business.

Connected my boot drive and tried to get it started, went straight back into the cycling thing again.

Used the jumper again and now it comes on, stays on, but no BIOS loading up on the screen.

Getting somewhere at least!

I've got this far with the original PSU, so now going to switch to the new one I borrowed to see if it makes a difference.
 
Looks like I'm in exactly the same boat as you Gaz, just swapped out the PSU and it's booting into bios consistently now. Almost back in business.
 
Alright, so Windows is booting up. My 500W Ocz PSU is ready for recycling I think.

What do you guys recommend to replace it on Overclockers these days? Fully modular please.

Thanks. :D
