i5 overclocked PC

[applx1]

Hello,

I recently posted an issue regarding my PC blue screening,

http://forums.overclockers.co.uk/showthread.php?p=23309789#post23309789

i5 Processor @ 4.01GHz
Windows 7 64bit
4GB RAM
M4 SSD

Since increasing the QPI/VTT voltage that seemed to have resolved the problem.

I am now faced with another problem (possibly linked to original) whereby my PC restarts sporadically. There is no BSOD or info crash report once it boots up again. The only information I have found is in the event log,

"The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly."

Any ideas or advice will be greatly appreciated?

TIA

Regards
Kishan

It might be worth saving your overclock settings, and put everything back to default. So standard clocks and all voltages on auto. If it stops it then it would more than likely be an unstable overclock.
