Hi all, I just put together a new system and have a problem that I just can't fix. I hope you can give me some ideas. System: Gigabyte GA X58A-UD3R MB Intel i7 920 Corsair TX750 PS OCZ Vertex SSD Win 7 64Bit ATI Radeon HD5770 850M 16MB (S/N L5H031205) My issue is that when I load the video driver the system loads all the way into the OS fine and then after about oh say 2-5 mins it just shuts down. If I boot into safe mode with and without networking it doesn't do it. If I delete the driver and boot up with standard VGA it also doesn't do it. I loaded the latest driver suite 10.7 and it does it every time. Ugh. Advice? Thanks.
