I just got a new computer, and it came with Windows Vista. I'm still getting used to it, but I don't have any big problems with it. Except one. Every so often, the tabs on my toolbar shift underneath my Start button, and even though I can see that they've moved to the left, I have to click where they're supposed to be to use them. Next, everything goes comatose and I have to restart my computer.

I'd like to avoid taking this bitch to the shop. Does anybody have any ideas, or had a similar experience?
