It's a built from scratch machine from years ago with a dedicated card. I may just have to reinstall windows.
Like Tech Analysis said... and if this machine is old enough to have an AGP video card slot... they are very sensitive to being fully seated. Even if not AGP, good idea to unseat and reseat video card and everything else except the PSU and the CPU.
Should do the easiest things first in troubleshooting.
