Laptop issues..

[bluef0x]

My GF got a new compaq laptop pretty recently from Costco. It's worked fine until now and there are a few problems...

First, She uses a mx510 I bought her... but when you unplug it from the USB windows automatically shutsdown and reboots. It's kind of a loose port so it can happen on accident quite easily.

Second, there are three buttons near the power button for decreasing, increasing, and muting the volume. If you use those the computer will sort-of freeze. You can still move the mouse cursor and ctrl-alt-delete but most programs stop respond and the "clicks" dont register at all- so you're forced to restart. Sometimes when you play music you can't do anything until the song finishes.

Anyone have any ideas? I've reformatted and it didn't fix anything.. Thanks.
