Weird Graphics glitch with my UE4

Hello everyone!
I recently bought a new pc and it came with a big problem.

As shown in this video

YoutubeLink

Every 15 minutes with the engine open, UE4 basically stops working properly on my computer. No dropdown menu appears when I click and apparently my video card as a whole is affected. The youtube videos keep playing but now no video, just sound. In fact, any video that I try to play on my PC, is just black.

As soon as I close the Engine, everything goes back to normal. Until another 15 minutes and everything breaks again.

My games all work smoothly when I’ve been playing for a long time. I only have problems with UE4.

My pc Specs:

Graphics: Gtx 1660 super

proc: i31010f

Ram: 8Gb

There’s a massive amount of stuff on here about this kind of thing. Apparently there is a fix from NVIDIA, but you’ll have to search their forums for it ( I can’t find it right now ).
