I have over clocked my cpu which is i7-3770k, to 4.5 ghz with right voltage. 1.22
And my motherboard died or pc wont turn on. So i swapped PSU to new one and still didn't work. I think its cmos battery prob but i just want to make sure. Because of this prob, i killed 2 motherboard and getting it replaced. It its not cpu, ram , psu , gpu. Problem. I need solution so bad....

My specs are...

Gigabyte z77 up4 motherboard. With h100i cooler
I7 3770k
16 gb ram
Gtx 680
750 w corsair psu



My cpu stays under 50 degree at load.

If anyone solve this, ill love you forever.

Mobo isnt touching any cable or case. I have corsair 650d , pretty huge one.
And i didnt touch any setting except for clock ratio setting.

Cpu, gpu, psu, all ok.

Maybe under/over voltage?
But cpu temps are like 24 degree at idle.

Load temp is 50 degree ish at 4.5ghz.

Last time i used the boost mode in motherboard, UEFI has setting that automatically sets clock ratio and stuff. And when i used that, my pc was freezing and making weird loop noises. And i couldnt turn it off so i had to force shutdown
