Hi , im not sure if anybody faced the problem before .
I managed to oc to 4.5ghz and ran all the prime95 approx 12hrs and it was stable for almost 3 weeks. Temp was around 50-60c while playing games.
Switched off all idle mode and standby/sleep etc as well.
I dont use my pc 24/7 so i shut them down daily.

But after 3 weeks im facing this problem :

- cpu fan jerking when booting now.
- will run slow at start then only reach optimal rpm
- now it wont start and auto shutdown and loop over and over again.

What can i do to troubleshoot this?
-scythe ashura/i5-2500k/asus-p8p67 pro/only normal ram 4gb

*sorry i got no screenshots to provide , i cant even get into windows now :/

whether you've reset your mobo to factory original setup?

Now it doesnt even go into bios. Previously i have already reset to optimal instead of the 4.5ghz profile

i cannot brain your vcore, dram clock and bclk. post cpuz here and other specs

What motherboard are you using?
What CPU cooler are you using?
Gigabyte has Dual-Bios so no need afraid if the bios haywire
Perform a Bios Reset by removing the CMOS Battery. For a detail guide, see here: http://lmgtfy.com/?q=reset+bios+removing+cmos+battery

Thank you for the reply i did try the mentioned above too .

Somehow i managed to get into bios again after reassembled everything ,Ignored the fan speed in bios and i could run the windows fine without fan ( thank god for the huge heatsink still on 40 degrees++). Returned the fan for warranty it was the Scythe Ashura fan faulty and oc again running fine for now
