Um. Maybe. (it's the home computer, I can't check). But if I do, it's been in there for ages.
Honestly, I think the computer's dying. It takes forever to boot up. I've gotten the C drive error twice in three days. The first time I rebooted and it worked ok. The second time was last night -- I decided to let it defrag while I slept, and so I started that and then woke up this morning to the C drive error. I hit control-alt-delete to reboot, went to put on makeup, and came back to a completely off computer.
