I bought a new harddrive and began installing all the software from scratch; OS > Programs > Drivers etc. Everything worked fine until I installed the driver for my vidio card (NVIDIA FX 5700 le). When I adjusted the resolution to fit the screen (1024 X 768) the screen became very unstable. It began to shake the move and eventually contort. I tried mess with the resolution some more and now the monitor doesn't display anything. There was an option to adjust the framerate as well as the resolution and I think I lowered it to a value I can't remember.
Usually I can just tinker around with something until I fix it but this problem causes me to not be able to see what's going on. Any help would be great.
