I have an RTX 2070, something similarly to this is happening to what you can imagine is a very new EVGA graphics card. I looked up this could be happening because of dust trapped inside overheating some components, this can be fixed by a restart only. Before opening up my graphics card to clean it and very possibly breaking it knowing myself could I have a second opinion about it? I spayed it with compressed air and cleaned it a few days ago and it worked fine until it started happening again. 1 minute into anything that causes it to overheat like CS:GO and this happens. Using something like minecraft and it can work fine for what looks to be forever.
