Hi all

My brothers pc has been fine untill today.
He turned it on this morning and it was fine but when he went to turn it on this afternoon he had a problem.
The pc powers on for around 2 seconds then turns off and this just keeps going in a cycle. It does not even get as far as any boot screnn so getting into the bios is impossible (and a waste of time as there isnt any display)
I have tried disconnecting both his ram and gcard 1 by 1 to see if i could identify a problem but had no luck. The only thing i did notice was on his motherboard where usually he has blue lights there were now none and when the pc has power for a few seconds i can quickly see what looks like 8 red lights on the motherboard. These seem to match up to the phase led and the nb phase led lights when looking at the motherboard manual.
Now i have no idea what could be wrong apart from maybe because he has a overclocked bundle from ocuk that maybe something has gone wrong because the only difference i could see was the difference in lights on the motherboard. My brothers specs are below.


"i7 920@4Ghz, Gigabyte X58A-UD3R, 6gig Patriot DDR3 C9 RAM
Saphire 5970 OC, HD audio, Gigaworks S750 7.1 speakers
2x 500gb SATA2 hard drives, Pioneer Blu-ray
Tagen 1100w psu, Cosmos S, Win 7 64. "


Thanks for any help
 
Sounds like your overclock has become unstable, try resetting the CMOS by removing the battery and removing the power cord or shorting the clear CMOS pins on the motherboard.
 
The sticky power button thing is not a option as the cosmos s has a touch sensitive power button.

As for the overclock being unstable.............i did consider hitting the cmos reset button on the rear of the motherboard as that model has one but my brother does not know how to overclock it again and as he has only recently got the overclocked bundle he didnt really want to reset it all to basic settings as he wanted and paid for a overclocked bundle
 
the bios settings for the overclock should be stored as a profile in the bios, so just reload that to get the 4ghz back
 
Hopefully Ocuk should have saved a profile in the BIOS, I think it's F11 or F12 within the BIOS.
 
Ok gonna try and reset the cmos via the button and see what happens.

Update......Reseting the cmos via the button did nothing.

Does anyone else think the motherboard has gone(and would that cause this problem)
The motherboard does usually have blue lights on standby mode but as i said in the op there are no lights on the mb in standby mode now

Try clearing CMOS by unplugging the PC and removing the battery for ~ 30s.

Have you tried using the onboard power button?

Also, if you could try a different PSU.

From what i can see the blue LEDs indicate overclocked CPU.
 
try removing the power button connector from the motherboard, and shorting the connection with a flat blade screwdriver or needle nose pliers
 
Ok guys gonna try all your suggestions 1 by 1 tommorow.
I think its either the mb or the psu.
I will update everyone tommorow....unless i manage to fix my bros pc then he can update ya all himself lol
 
Can we please just eliminate the button before we start going all technical. Unplug the power button then momentarily short the two socket terminals together.

Next, the PSU. Jump start the PSU with a paperclip to see if it works properly.

These simple fixes may save you hours of troubleshooting these technical things or even returning it to OCUK for repair. From experience this pays off. I have done many stupid things like that and spend days trawling though deep BIOS settings when all that needed doing was reseating the GPU.
