Overclocking problem, please help!

[Mykillcode]

I decided to do a manual overclock of my 8700k yesterday. I dialed in all my settings and ran a few stress tests, finished off with running Prime95 for an hour to check for instabilities. Everything went fine. But then today started to play Destiny 2 and my main screen kept on going black then coming back (computer still running almost like the source was being changed). I changed over my main screen so I was playing on my secondary and that one was fine but the other continued to go blank then come back on again.

 

I checked all the cables and everything was fine, so I thought I would remove the OC that I did. That was about 12 hours ago now and I have had no problems with my screen. 

Does anyone have any suggestions that would be great. I have had an auto OC on this before and it was fine. 

 

Specs:

8700k

Asus Maximus XI Hero Z390

Fractal Design 360 AIO cooler

RTX 2070

 

OC:

5Ghz

1.350 Volts

XMP1

That doesn't really sound like a CPU overclock issue, although that could manifest in a lot of different ways.

 

What's your power supply?

 

Are your graphics drivers up to date?

Probably a touch or two low on v-core. Mine won't do 5ghz on that low (1.350v) stable either. Woof above, look at his sig for reference. 1.385v.
