[tokra]

Hy!

I have an i5 2500k and i tried to overclock it to 4.0GHZ.I tought it was nothing accepted the changes without changing the voltage. After this I rebooted I cant seem to get past the BIOS screen. When it is on the BIOS screen sometimes it beeps (The regular turning on short beep)
Motherboard: Gigabyte z77-ds3h
Cpu: i5 2500k
Gpu: GTX 780
Ram: already tried switching them and removing 1 or the other
PSU: FSP RAIDER 650

Any help would be grateful!

Reset your bios to default and see if it will start up then.

Do you have the aftermarket cpu cooler? I have the 212plus.
I just test my i5 few minutes and am typing now, you don't need change anything in the BIOS, I only change the multi to 40X then just boot the PC, the temp is in 39-42C high and 27-30C low side.

Already tried resetting bios, with the Cmos battery removal.
