Question Big black walls while gaming

Welcome to the forums, newcomer!

While im playing games
This is a screenshot of the problem:

Is this confined to one game alone?

Your specs is missing one crucial component, what is the make and model of your PSU and it's age? While you follow up with the PSU info, can you see if your motherboard is pending any BIOS updates? Check to see if your OS is also pending an update. Once you've verified that both the (motherboard)BIOS is up to date alongside the OS, use DDU to remove all GPU drivers, then manually reinstall with the latest driver sourced from Nvidia's support site in an elevated command, i.e, Right click installer>Run as Administrator.

Hi!,,No its not confined to one game, i have seen the black walls while playing, EFT, Apex legends and PUBG. I did have updates both on the BIOS and OS, i have updated the Bios driver but i cant update my OS because my windows update dosent work. I did what u suggested about removing all my GPU drivers and manually install the latest driver update, but the black walls still show up. I dont know what model or make my PSU is because its a prebuilt which i have recently upgraded the Motherboard and CPU on.
