Hi I got my laptop about 3 months ago bought it new. Its a HP G7-1365dx windows 7 64 bit laptop. Everything has been fine with until today. I started playing League of Legends then the laptop froze in mid game. I restarted and it froze again while in firefox. I ran virus scans and registry scans and nothing came up there. It is just freezing after I log in. Also weirdly my wifi card disappeared in device manager and showed back up after restarting the laptop again. My need to resinstall or update. Can someone help me with this problem?

Someone told me it might be overheatting, but I ran speedfan so I know that isnt the problem.
