My computer keeps randomly restarting and, while I thought it was because of service pack 2, I reformatted this weekend, and the restarts continue (not on as grand a scale, but they're still there). I currently use a 330 watt ps, and was wondering if it would be worth it to upgrade. I've been looking at the antec Neopower 480, because I like the idea of deciding yourself which cables come out of your ps. Good choice? Is there a better one? Is it even possible that my restarts are because of my ps? Any input would be appreciated.
