I'm running Parallels 3.0 on my MacBook. I have XP and Vista installed, and both were working fine untill about 10 minutes ago. I installed Parallels Tools in Vista, and when I was asked to restart, I got the blue screen of death ("A problem has been detected and Windows has been shut down to prevent damage to your computer"). It boots up in Safe Mode, however I cannot uninstall Parallels Tools because the installation was never completed successfully. One time, when it was booting up it didn't give me the blue screen, however it just went black and the cursor appeared in the centre of the screen. Any ideas? Thankyou, Nick.
