Laptop suddenly slow when gaming

[Cheezylemon]

Hey guys, a while back my laptop was running pretty well when playing games such as gmod 13 with 20-40 fps on some of my favorite servers, and running tf2 15-40 fps on servers. Something that you should know is that my brother had previously dropped the laptop, breaking a usb port and maybe rattling the fan. Also, this laptop has some cooling problems, I have to use a cooling pad and a cheap personal fan to keep it from Overheating. So yeah here are the specs from speccy- Operating System
