You leaving that on all the time? Test with it unplugged?
Maybe you should go back to the previous NVideo driver files.
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:
