90% of the time, when your computer gives you a 'Blue screen of Death' (BSOD) on boot up, it's due to a corrupted registry. A lot of things can cause this to happen, but normally it's due to the computer suddenly loosing power during read/write, emphasis on WRITE, operations.

Two options that I use for my customers when this happens.....

Pull the H/D and run Chkdsk \F on it from another system. This should fix any physical errors on the drive by recovering and moving any data that can be found. Once you boot up, you'll get a msg saying what files are still missing from the damaged drive. Make a note of them and then remove the drive again. Copy files from a good working system over to the bad drive and try to reboot.

Second option is to do a low level format using a disk drive utility that works for your drive. I use Emergency Boot CD and Ultimate Boot CD for these utilities. Once the format is finished, this may take quite some time depending on the size, try and reinstall the O/S.
