Overclocking - Cant Boot

[BenGill]

Hi,

I've previously overclocked my CPU to 4.9ghz and it ran fine but the temps were a little high so I took it down to 4.7ghz where its been running perfectly for 2 weeks.

I was getting around 67°C max so I thought I could get 4.8ghz out of it. I went into my bios and did this - now my pc says its diagnosing every time and it won't boot. I've completely reverted my oc back to stock, ive cleared cmos, its still not working. Could anyone help me please? :)
