No computer = no blog

My computer has died a sad death.
Luckily I had started backing up all of my stuff before it died.
I didn't back up itunes or photos. Hopefully, I can still get those off.
I'm going to bake the tech guys at Prescott College cookies.... for this will be the third time they've helped me pull data off my hard drive when my computer is broken.
I would appreciate any suggestions...
I can't get my computer to boot. It does from the dell startup screen (where you can press f2 or f8 to enter setup) to the windows xp start up screen. then it flashes to a blue error screen.
then it goes to a selection screen where i can choose to start in safe mode, etc. no matter what i choose, it goes to the start up screen, the windows xp start up screen, to the blue screen, to the selection screen.
I changed the boot order and tried booting from a disk. I tried system recovery and i also tried reinstalling xp. both options did nothing but start the startup screen-error screen loop over again. I looked up the error (Stop 0x00000024) on mircrosoft.com and they recommended running chkdsk, and removing the last program i installed.... but i can't get to a command prompt.
The last program I installed was limewire, and I think it may have been what crashed it. Any suggestions for how to uninstall it?
