I feel that my computer has started to lose it's heat after I bought it a month ago. The internet has been slow ever since I got the shell-case for my new MacBook, and recently my Firefox has been freezing, and all of my programs have been laggy. Also, I can't get TF2 to work properly, I load it up to not have it let me click any buttons, although the game hasn't frozen, and it's hard to connect to a server (and stay connected), despite my friends having perfect connections. It makes me frustrated and perplexed that I bought this computer a month ago, bought all of this extra care for it (and showed it care), and it is just crapping out on me like this :/, what gives?
