Question Pc freezing when i see the bios logo

[AxelG]

I was playing a game with a small overclock on a i5 6600k, (4,3ghz) then my pc just decided to freeze. I held the restart button as ive done many times before when i had a bit higher overclocks and it freezes (4,4-4,8ghz). It seems as if i could overclock less and less and my pc still freezes, so i think something else makes my pc freeze. Anyways, when i tried booting up again i saw the GIGABYTE logo and some info like press del to get into bios and f12 to choose boot order and stuff like that. But the pc just freezes, i cant click any button and it wont boot further. Anyone else having this issue/have had it before?

I've tried resetting the CMOS and taking in and out ram and swiching slots, same thing happens every time.

the psu and gpu is from a prebuilt (ideacentre y710), all the other stuff i purchased later.

What do you mean by this?
The system bearly uses 200w the cpu avrages 40-70W under load depending if its oc or not and the gpu uses 120W max, 140W with overclock. 140+70= 210W. 450-210 = 240 W left over to ssd,hdd,ram,motherboard,led etc.
