Hello, Since two days ago my gaming fps has dropped incredibly low. I used to play League of Legends at max setting be at a stable 60 fps and since Wednesday it has dropped to a 15 with all settings dropped to a minimum. After restarting my computer it sometime works fine for the first 5 minutes (In Max Settings) but after that there is a massive drop even when i revert back to low quality.
Windows 7 Home Premium 64-bit 6.1 build 7601
Intel Core i5 CPU @ 2.67 GHz Quad Core
4096 MB RAM
NVIDIA GeForce GTX 460
Ive also tried Civilization 5 and it took about 5 minutes to pass the loading screen and after that it was completely frozen (No mouse Control). My computer is also pretty old. I think it is about 7-10 years but im not sure but it worked perfectly fine up until this point.
If im missing any specs you would need please let me know and ive looked around and couldnt find anything similar to my problem please help.
