My computer is 3 years old, an Alienware Aurora R5. It hasn't been running as well as I think it should, and I am not able to play a lot of games with decent FPS. I haven't tried in a while but last summer when I tried to factory reset it, it gave me an error, not letting me reset it. I tried again a month later and still got the same error. I also noticed when I would be able to factory reset prior to that error, I would barely notice any improvement. Do I just need to invest in a new computer?
