Gigabyte 3080 Hash Rate Decreased 95 MH/s - 65 MH/s

A couple months ago I started mining with my Gigabyte 3080 casually and got hash rates that varied between 88-105 MH/s. I consistently left the setup running and monitored temperatures until randomly one day I noticed my hash rate had plummeted. I've tried overclocking, undervolting, restoring my computer, and other methods but I am stuck at 65 MH/s now. I am really confused and am looking for any help that could potentially solve my issues. I also believe I've noticed a drop in frame rate in games as well. Thanks for reading!
