How far does it get into booting, can you get into the BIOS?

Have you checked all your internal and external connections?

the screen is still black on the monitor when the power switches off.

it doesnt do it all the time does it maybe twice a month

so can easily get to bios

the system is a pre built overclockers build so the overclock has been done by them these are tested surely or?

i will check all conections now

thankyou for the quick replys

Sounds like your mobo is dying my old Q6600 rig died in the same way, was sad day loved that Cpu

I hope not its not even 6 months old!!
Might just send the system back to overclockers and get them to check It it's under warranty so... Will phone them and see what they say.

Hahaha yeah pretty much,but then switches back on again.
It only does it every so often like a couple of times a month
