Hi, I've Overclock my E6300 to 2.8GHZ without any issue for 2 years until now. When I've able to pass POST with that speed, I ran Orthos for 12 hours stable. When I Restart, The PC cannot boot up and the LCD show a blinking power light. The only way to boot up is to turn off the PC for a few minutes and the PC will boot with it's default settings.

The issue is even If I OC by 2.0GHZ, I've still experience the same thing, Only stock speed have no issue.

Using F14 Bios.

My Spec.

E6300 1.8GHZ
5850
2GB DDR667 Value Ram
450W PSU True Power
