About 1 year ago I bought a PC. It worked fine and it could run all the games I played on 60+ fps. After a year I decided to upgrade my PC. I bought a new SSD and a 1060 graphic card. It worked perfectly fine at the beginning. I had 100+ fps on GTA 5. After 1-2 months my fps suddenly dropped down to 40+50 fps. I've tried many different things to fix it but nothing seems to work. I don't know what happened but i really hope someone can help me solve this problem.
