Screen going black for a second and GPU usage going 0-100%

May 28, 2018 1:40AM PDT

Got a new pc 6 months ago works fine. 2 weeks ago the screen starts freezing up and going black (but the monitor is still on) while playing games the screen goes black and then on again but the game crashes. I installed new drivers even a new bios nothing changed. Tested ram with memtest no errors what so ever still nothing. Here are screenshots of performance while gaming:

As you can see it's consantly spiking up and down. And games i should be able to play at max settings no problem run barely at 10fps.
And it's not just games the system even while idling does the same thing. Sometimes ti freezes up so bad i have to restart. So any ideas what could it be and how to fix it?
Here are the specs:

You leaving that on all the time? Test with it unplugged?

Maybe you should go back to the previous NVideo driver files.

Yes i do but the problem persists even with the cam unplugged.
I will try going to older nvidia drivers. I will also try reinstalling windows because when i did a windows update 2 days ago the problem went away but when i started the pc up again the problem came back.
