Instead of using gui try ctrl-alt F2 key maybe. See if you have console access on other sessions. log in on bash shell and edit gui settings. I suspect the video settings are wrong but that is a wild guess. dunno? "Best Practices", Event viewer, host file, perfmon, antivirus, anti-spyware, Live CD's, backups, are in my top 10
