Basically I don't know much about computers so i apologise ahead of time if i am just being stupid for something, however I just don't know how my computer went from running any game flawlessly for me to not being able to perform simple tasks without freezing up and just overall running slower than it used to. This happened suddenly within a single night and i don't know what could've done it. If anyone could help me with this issue i would be eternally grateful.
