So i got this cpu cooler just recently and decided to overclock i5 2500k.I went and looked some guides and things about oc'ing and figured out what to do.My clockspeed is at 4.5 ghz with manual set voltage to 1.280.Everything was great and i ran intel burn test for a few hours and also mainly battlefield 1 because i remembered it could use up to 99% of my cpu in the past so i thought it was a good sign (since its mostly what i play).I set my bios options like that so when my pc is idle the clockspeed goes down to 1.6 ghz and the temps are just nice and low how i like it.
Today when i tried to start my pc up there was nothing on the screen,only pc leds were on for like 3 seconds and after that my pc restarted itself and went into bios,i didnt change any settings and pressed F10 and enter and after that my pc successfully booted and i was again able to stresstest and play games just like everything is alright.After that i tried to shutdown the pc just to check if its gonna boot now and the same thing as above happened.

I have C1 and EIST enabled in bios.
I would really like this to work since i dont want to run my cpu at 4500mhz all the time but i also want it to be stable like it was for first few days.Thanks for reading and i hope we can manage to work something out ^^
