New CPU, no display

[Gwnplayz]

Hello people of this forum,

 

I have bought a used cpu (i5 6600k), as an upgrade for what I have now (pentium g4400), after having it installed I tried booting but I got no display. 

I am sure that I installed the cpu correctly and all the power connectors are connected. All the fans run and the pc seems like its running but there is just no display.

I have tried changing the RAM slots, but that didn't help anything. I now have reinstalled my old cpu and my pc works fine. I really trust the seller of the used cpu, so I don't think that I got scammed.

Could there be other factors or things that cause this problem? I know that the mobo supports the cpu, but my knowledge ends there. Maybe something to do with bios?

 

My specs are:

i5 6600k (pc works with the pentium g4400)

Asus prime h270-plus mobo

2x 8 GB Corsair Vengeance RAM

Asrock rx 570 8g gpu

CoolerMaster MWE 650w psu

Seagate barracuda 1TB hdd

 

Thank you for your time, I hope someone has the solution.

Have you reset the bios?

Pull the coin battery on the motherboard for 1 minute and put it back.

If not working, put the pentium back and update the bios.
