Now have a clean, well working netbook.
Used The Toshiba hidden partition to wipe and re-install XP. It couldn't be simpler.
I opened IE and tried to download SP3. The download wouldn't work and then IE started crashing. Decided to install Google Chrome and got SP3. Took 3 hours. Got AVG. Everything is working well, couldn't be happier.
Just finished downloading Sketchup.
