Ok so oddly enough after I change a couple of settings in the kernel. This last time it was simply

In hardware monitoring support. I reboot and can't get in.X. I re.emerge NVIDIA drivers.and it still won't work

If I go back in the kernel and change these settings back. It still won't [/b]work. Any ideas

You can try the module-rebuild tool.

Check: http://www.gentoo.org/doc/en/kernel-upgrade.xml

This is a common problem with out-of-tree graphics drivers. Check that the kernel picked by the nVidia drivers build is the kernel you are running. If I am right, your nvidia.ko is incompatible with the running kernel, so the kernel refuses to load it. Xorg then fails to start because the user-side nVidia libraries cannot talk to the nVidia kernel driver.

If you still have trouble, please post the output of emerge --info ; emerge --pretend --verbose x11-drivers/nvidia-drivers.

You could also try switching to the open drivers, which keep their kernel component in-tree and avoid this problem.
