When I first bought my PC, it was running fine. But then 2 months ago, it started having issues, the home screen began to lag, the applications began to slow down when it came to opening them (which is weird because I have an SSD), and then the worst of all, any game that uses my graphics card, after about 10 minutes of opening it, just freezes, then after about 30 seconds unfreezes and says "Display driver stopped responding and has recovered" It's almost impossible to play any games! I usually run at around 400 fps in CS:GO, but then after these problems started occurring, my fps dropped to 200, on lowest settings (which I wouldn't mind) but when I moved my mouse, it dropped to 70 frames (for some reason my PC needs to be at above 144 fps otherwise it starts acting very glitchy.) Help?
