As of recently, many games I used to play and could easily run all started crashing. They all crash within a minute, and these games include far cry 5, Honkai starrail, and Fortnite. I also used to be able to run hogwarts legacy, but now it won’t even start.

The reason why I’m thinking of reinstalling windows is because I’ve tried multiple online solutions, though to no avail. Im really lost on what to do, any help? Thanks

Specs (old but able to run those games at low/medium graphics) : i7-4790k Gtx 960 16 gigs of ddr3
