I've been rather stumped with a problem I've had with my PC of late and haven't been able to find anything that addresses it in my search for answers.
What's happening I hear you think - well on a fairly regular basis recently I'll walk away from the computer for a few minutes leaving the monitor on, when I return my desktop has gone black. I can't see any of the windows/programs I had open previously, I can however still see the explorer bar running across the bottom of the screen with all the programs/windows I have open still appearing there. I can also still see the miniature version pop up when I put the mouse over the program tabs. If i move the mouse off the explorer bar into the desktop area, the cursor disappears. Closing all the programs doesn't help. Sometimes when I hit ctrl-alt-del my desktop comes back - sometimes I need to log out to end the problem.
Does anyone have any ideas about what the problem might be?
