I bought my gaming pc like 4 months ago and i could handle all games from Arma 3 on high settings to minecraft and run them all really good. But as of like last week i cant handle any games really i went from being able to get 300 fps max on minecraft to not being able to get above 30. And i have razer game booster to close all unwanted applications taking up memory from the processor and it still doesnt help and ive ran a virus scan like twice already and ive got no idea what to do now anything will help. My pc specs are fx-6300 and r9 270x. I built the pc myself, would restoring ym computer help? And if i restore it would it uninstall windows 8 from the hard drive?
