Clutch, thank you so much for responding!
I just checked these:
NTFS permissions: fine, everyone has read, I have all permissions
file extensions: all files, html, jpg, what ever... none will work, it just says "file not found" when you try to go to the site, or a specific location.
Security Util: I was ussing IISLockdown, I ran it again to undo the settings, it had an effect, the error slightly changed, but still the same problem. URLScan, I don't believe that is installed.
Logs: How do I get to the logs? I looked in IIS, didn't see them (maybe i'm blind?), also looked in the event viewer. Found no errors but some information for IISCTLS, what ever that is... I believe these 4 "infos" were made when I did an "undo" on IISLockdown.
I am going to try to uninstall IIS, and the reinstall it.
