Starting about two weeks ago, the icons in my task bar and start menu have become really jacked up after I've used the computer for about an hour. I can't see the icons, but if I click where I know they should be stuff still opens. If I open my start menu, I just see a transparent window with no icons in it. Closing and restarting explorer.exe fixes the problem but only for a while. Here's a picture of the taskbar. I tried taking a screenshow of the start menu but it wouldn't let me.
