Hello, when trying to access Graphics Properties by right clicking on the desktop I get a pop-up error saying: C:windows\system32\gfxUI.exe, A device attached to the system is not functioning.

I'm running Windows 7.

I'm not sure what the issue that caused this was, but system seems slow running Firefox. I thought I was infected by something so I troubleshooted at the malware/virus forum on techspot. After going throught steps, person who helped said I was clean.

Any thoughts on what this error is and how to fix?

Thank you.
