Question Fullscreen causes screen to flash black and return me to Desktop

[Eksoduss]

Borderless and Windowed work perfectly fine.

All Nvidia Drivers are up to date.

This doesn't happen with all applications, but specifically games like Rainbow 6 Siege and non-16:9 games like Touhou 06 (before it could be forced into fullscreen, now it doesnt work anymore.

The exact process is like this:
- Application opens
- Screen flashes black, makes the same sound it does when it turns off
- Application is visible for 1 Second
- Screen flashes black, same sound
- Back to Desktop

With R6, this person had the same problem:

Can't go fullscreen? :: Tom Clancy's Rainbow Six Siege Player Support

I try setting the display to fullscreen, but it just tabs me out of it back to the desktop whenever I try

-> Changing the Nvidia Control Panel settings didn't help.

This also sounds exactly like my problem:

New monitor flashing black while in full screen mode.

I got a new monitor, Acer Predator X34p Intel i7 6700K GTX 1080 W10, up to date. GPU drivers up to date. Prior screen was a 144 Hz 2560x1440. This one is 120 Hz (OC from 100 Hz) 3440x1440. Flashing black happens for a second, then goes back to what it should be, then flashes. It flashes...

Welcome to the forums, newcomer!

I'd start with seeing if your prebuilt's motherboard has any BIOS updates pending, then check to see if your OS is pending any updates. As for your GPU, use DDU to uninstall all GPU drivers from your platform, then manually reinstall with the latest GPU drivers listed on Nvidia's support site, in an elevated command, i.e, Right click installer>Run as Administrator.

What is the make and model of your PSU? or rather what is the SKU to your Dell Prebuilt?

Sorry for the late reply, but I've now followed al of the steps you recommended (BIOS Update, OS Update, GPU Driver reinstall), but sadly, nothing has worked so far. The only thing that happened were rampant crashes after the BIOS-Update, but I (hopefully) have fixed that myself.

Can you also tell me what an SKU is? I looked it up, but couldnt find anything.

EDIT: Nevermind, PC still keeps crashing, at random times and according to the Event Viewer due to a cache hierarchy error. Also don't know what to do about that.
