I had a 7600gt that had overheated and was artifacting on me and all. Since then I replaced the motherboard, CPU, RAM, and power supply. I have and GTS 250 now. Been working great for the last three months. Now my computer freezes whenever I play video such as from hulu.com or from my hd and have to reboot. Games play fine but sometime when I try to exit out system hangs and have to reboot. I thought it could be spyware or virus related, but nothing came up. I'm sure the last card overheated because fan was bad. Was making weird noised and stopped periodically. Can my new video card be crapping out on me already or should I reload windows again?
