980ti with CPU overclock issue

[Tackle_Berry]

I have been running my watercooled 3770k overclocked at 4.8 and a 680 with no issues for the last two years.

Today I installed an Evga 980ti SC+ with the stock cooler (loop is now just doing CPU for the time being) on start up I was getting Windows boot errors where it would say PC repair and the windows 10 logo would just spin and then load a repair screen or I would just end up with a black screen after the motherboard flash screen.

I figured that maybe my C drive was not reading correctly so I restored it to a Macrium image, this then failed halfway. I then done a clean install of Windows 10 this worked up until desktop and then it would freeze, on restart I got the same error messages again.

After playing around I turned my overclock off entirely and it now seems stable with no more error messages on start. Could it be my Corsair AX850 is not powerful enough?

Your PSU is more than enough, can you try redoing the overclock in stages.

It's been a few years since I have overclocked anything. I will re-read a guide and start over if it's not the PSU.

One thing, just double check the CPU temps in the BIOS.

Country temps?
