I have old GTX 970 graphic card and i7 CPU. I have been playing some games regularly, playing in full HD new games like Battlefield 1 without problems, and suddenly, yesterday, when I opened such a game, I had 1 fps. Literally unplayable. Like if my GPU was a potato. When I opened a 12 years old game that I have been playing on this PC for year, all textures were white. When I opened a game (Rainbow Six: siege) I got this message: Installed graphic card driver is not supported, update graphic card driver. This message wasnt there before. So I tried to open device manager to try to update GPU driver, but I got this brand new error message: "This operation has been cancelled due to restrictions in an effect on this computer. Please try to contact system administrator". So I couldnt even open device manager. I dont use antivirus. I recently reinstalled PC, and I dont want to do that all again. When I wrote a simple code in Visual studio 2 days ago (Console App .NET), VS crashed twice. I can still without any problems use apps like browser, youtube, discord.
