Sound muting/un-muting rapidly, have to press keys twice, etc.
About an hour ago Windows 7 went on the fritz. The sound rapidly mutes and un-mutes, I intermittently have to press the windows key (as well as some other keys) more than once, my start menu pins disappeared, and sometimes I'm clicking on buttons or menus and have to click twice.
I don't believe I changed any system settings or installed/uninstalled anything around the time this started happening.
I ran check disk from "Computer->disk->properties->tools->Check now" and it rebooted and took perhaps half an hour to scan, then started up (I didn't see any messages about errors).
I tried disabling all startup programs and services (except for Microsoft's), but the issues persisted. Here's a video of the crazy mute/un-muting problem:

Besides re-installing Windows 7, which I really don't have time to do right now, what can I do to try and fix this?
