I play on a laptop with a GTX 1650. All my games started lagging one day for no apparent. There were no recent Windows update But I did update my Nvidia drivers three days prior to the beginning of the lag. But the days leading up to the lags were fine and all my games ran without any issues. My CPU and GPU temps are same as before. This has happened before and I had to reinstall windows to solve the problem. But now I'm unwilling to do so because I have a lot of important files now. What must I do?
