Could be failing capacitors in the PSU. But before changing the PSU, try changing the CMOS battery. It could be weak and needs a shot of juice to wake it up. A PC can't boot with a dead CMOS battery.

!!!!!!!!!!!!!!!!!!!!!!!!!SOLVED!!!!!!!!!!!!!!!!!!!!!!!!!!

All I had to do was update the BIOS. The P67 Chipset BIOS has been known to have problems when over clocking and most motherboard manufacturers have released a stability update for the BIOS. 30 seconds to flash the BIOS and voila!

But thanks though @clutchc
