Using the Print Screen button on my Logitech K120 wired keyboard totally locks up the computer. This problem has also occurred in Safe Mode as well. I've tried uninstalling and re installing all relevant drivers, but the problem persists. The On-Screen Keyboard works just as it should. Signing into Skype also locks up the computer in the same way. The computer becomes totally unresponsive, and requires a forced shutdown using the physical power button on the case. I've uninstalled and re installed using Add/Remove Programs, as well as Revo Uninstaller Pro, including cleaning all leftovers using Revo and/or CCleaner. I've scrounged the recesses of the web to try and resolve these issues, but no other forum posts seem to relate exactly to what I'm dealing with. Any help would be greatly appreciated, as I greatly miss using these.
