Have to send my laptop in for repairs

My laptop has been displaying some unusual behavior lately and it finally prompted me to contact Toshiba.

Basically starting last week, the screen would go to a solid color and I could never get back to the OS. Hard powering the laptop wouldn’t work either. Even time it happens, I have to unplug it and pull the battery for a few minutes.

Last night, I reinstalled XP to see if it was a problem with the OS, but it’s locked up twice already.

So Toshiba is sending out a box so I can send it in for repairs. I’m really curious what they will find. My guess would be something with the graphics chip.
