first of all i didnt buy it i got it for christmas and second i didnt put vista on there it came installed (it said on the box: Acer Aspire 5315 with Vista

the answer is by inconclusive_conjunction :
You can't blame Vista because you bought a crappy low-end laptop that would have a hard enough time running XP, let alone Vista.
