My laptop was working well with windows xp, I inserted Bluetooth in the USB and it says driver cd needed, so i inserted the drivers cd came with the bluetooth device. After that I installed the drivers, after the installation completed it requires to restart, so i restarted but the computer can not restaret just trying to start but shutdown.I tried to start is in safemode but the same then i formated the hard disk and tried to reinstall windows xp but when file copying completes and message came that your computer will be restarted after that a blue screen appears with a message 4201.cpi and i formated again and tried with another xp cd same thing, then i tried to install windows 98 it worked and after that i installed Windows Vista, it worked but it is 30 days evaluation only.So i again formated and tried to install windows xp but not working same thing after copying the files it stop on a blue screen.

Sounds like a CD-ROM might be scratched or somehow the files got corrupted.
