I bought a laptop for school and it came with windows 8. The laptop I bought is Acer® Aspire (V5-552G-8409). I installed windows 7 home premium on it and installed all the required drivers from Acer's website. I use the laptop in school and at home for my homework. The laptop keeps freezing when I use it at home after about 30-45 mins. I think it may be because it is overheating but I am not sure. Should I buy a cooling pad for it? The freezing only happens at home when I'm using in on my lap but not in class when it is on a desk.
