So, I usually play csgo on max settings and get around 150 fps but today I opened up csgo and in game i was getting between 5 to 30 fps. I rebooted my pc several times but this didn't help as well as updating all my drivers. I went to check my cpu usage and it will remain on 100% even when nothing is opened. I then checked my cpu temp and it stays on 70 degrees when idled and 90 degrees when all i have open is a browser. Ive been seraching for a resoultion all day and still have no ideas how to fix this problem. Any ideas?
