i5 7600 fresh out of the box 100% usage

[CVink]

Hey

So yesterday i installed my new cpu: i5 7600. When i first booted up my pc i check task manager to see if it recognised the new hardware but i noticed very quickly that my cpu was constantly at 100% usage. I figured this had something to do with drivers so i went ahead and installed all new drivers and updated the old ones. This did not solve the problem. I also cannot check my cpu temperatures with OpenHardwareMonitor anymore. I have to go into the Bios for this. Tho when i went into bios the temperature displayed 31°c which to me seems very cool for a cpu in general. So i tried some games and they ran just fine and it doesn't feel like the cpu is at full load. I have even tried removing the overclock off my GPU which shouldn't really make a difference and it didn't.

Can anyone explain to me what is causing this? or how i can fix this?

Kind regards Nanoid

Edit: trying fresh windows install i'll let you guys know if this fixes anything, in the meantime i would still apreciate possible solutions.
