maybe it is bad..

Yeah. It's like my dad's computer when he lived in his trailor. That thing had no trees covering it and no insulation, so it would heat up like a pressure cooker in the summer unless you kept the windows open and the fans on. My sister would ignore this and keep the damn windows shut (I don't know how she could stand it), and hanging out in the same room as the computer all day, this had some adverse effects. I'd come in and start playing a game, and the thing would start beeping like a motherfucker. After opening the window, turning on the fan, and letting it sit for about 30 minutes, it worked perfectly.
