It did boot again but froze completely after a few seconds but did not bsod. When I restarted it didn't manage to boot all the way but just froze on the 'start windows normally or in safe mode' screen. The third time It did boot but at a much slower speed my mouse/keyboard did not work at any point during the bootup however it did boot all the way and everything worked fine for a little longer but has frozen again without bsod.

Those are all set and the qpi/vtt is 1.395 which is 1 setting above 1.375. It did boot but froze again after a few minutes. I might just think about resetting everything and leaving it at 3.2ghz as it seems to be consistently unstable.
Yeah the performance I was having before with the 4ghz was great so it would be a shame to revert all the way back to 3.2 perhaps 3.8 would be a good compromise. In the mean time to reset everything is there an option in the bios? f6: fail safe defaults or f7: optimized defaults? If I reset everything I take it I should still leave the qpi/vtt to 1.315?
I did load the optimised defaults but the cpu and everything is still running at 4ghz. The multiplier, bclk and other settins has stayed the same. Completely default bios settings would be ideal then I can work on the oc later.
you can clear cmos then,either at the back if your board has the button or popping out the mb battery for a few minutes,then re enter any bios settings you need,ahci and qpi/vtt voltage ect
Yeah I've got the battery out so will leave that for a few minutes. The only setting I know I need at the moment is the qpi/vtt so I will just leave everything else I think. Maybe 3.8ghz would be slightly more stable.
Thanks for all the help wazza.
Okay now upon startup the keyboard/mouse will not work and I can only enter startup repair where it wants to do a system restore. I can't even get into bios
EDIT- I took at the battery again and when I put it back in I was able to enter the bios immediately but after changing the qpi/vtt I am then unable to select 'boot windows normally' as the keyboard ceases to work however the keyboard and mouse work when system repair starts.
It has booted now but that was some strange behaviour.
Its wireless with the 'wireless signal' coming from the hub plugged in via usb. It's strange but anyways everything is working great now. Don't worry about it you have got my pc back up and running and as long as its stable at 3.2 I am happier than if I'm getting constant crashing or bluescreens with 4ghz. I may think about moving up to 3.8 but I'll have a think. Is there a place to get all the right settings without having to keep nagging you as you have given me more than enough help.
Cheers
