If you have this problem, chances are you have an HP.
If not, the method to fix it may be similar.
The issue is generally caused by another program on your computer taking the "ctrl+shift+c" shortcut. The good news is, it's relatively easy to fix.
First, go to your desktop and hit "ctrl+shift+c" to bring up whatever program is taking up the shortcut. If something pops up, find it in the start menu, right-click its shortcut and go to properties then under "shortcut key" make sure it says "none" (if not, click in the box and press delete).
If nothing pops up when you hit "ctrl+shift+c" and you're using an HP, chances are it's a program called "HP Health Check" - some wiseguys at HP decided it would be a good idea to take up your "ctrl+shift+c" shortcut with this fairly useless program.
If this doesn't fix your problems, that is, if pressing "ctrl+shift+c" doesn't make anything pop up and "HP Health Check" hasn't got the shortcut, check what other background processes you've got going on. If you're running something like xfire or another chat program, make sure you haven't assigned "ctrl+shift+c" as one of its shortcuts.
