I was doing some tweaking on my new evga mobo. I set the fsb too high, and had to reset cmos, the led display came up FF, but no post. After several attempts, and no post, I pulled the battery, and got things going again. But rhen every time I try to use any of the Nvtune items the system hardlocks as soon as it tries to load.So I reinstalled windows, reloaded the bios, and am lost for any explanation, other than the northbridge died somewhat. Anybody have that sort of problem, or solution?
