Heya,
Since a few weeks i have a flickering screen when starting up my pc. In the beginning, the flickering would stop after a few minutes and my screen was just fine. Lately it takes way longer for the screen to be normal again, around 30 minutes or so. I checked if the screen is broken, it isn't. It's also set to the right refresh rate (60). I do have one freaking old video card (NVDIA GTX 770) so that might have something to do with it. I Googled all possible solutions except for one, which is to completely remove the 'stearing programme' (if thats what its called in English), which means my video card I think, and then restart pc and reinstall the video card. Afraid that it might break or will stop from working I thought I'd ask here first for some easier solutions or people who dealt with this before.
When my screen is only put in an outlet and not connected with my pc, the screen is just fine and isn't flickering, so I really think it has something to do with the pc.
Any help is appreciated
