    Just before windows begins to load, start pushing the "F8" key to get the Safe Mode menu. Try launchin windows in safe mode to see if the issue persists. If you successfully login to safe mode, try checking the Event Log for an error consistent with your rebooting problem. You can also try a system restore from safe mode to reset your PC to a time before the reboots started occuring. Also try disabling any unnecessary startup programs through msconfig (start menu -> Run -> type: msconfig <press enter> -> startup tab).

    If you can not boot into safe mode, you can check to see if you have picked up any viruses from the recovery console. You can access the recovery console by inserting your Windows XP CD and rebooting and following the simple onscreen instructions. When you are in the console you should type the following:

    dir <systemdrive>\docume~1\<username>\startm~1\programs\startup

    if there is nothing present then also check this folder:

    dir <systemdrive>\docume~1\alluse~1\startm~1\programs\startup

    If your username has more than 8 characters in, shorten it down to 6 characters and add ~1 to it.

    Normally what is very common is the virus uses the "shutdown.exe" program in the system32 folder, but as a shortcut (for example, shutdown.exe -r -t01), and if it is present it shows in the folder as ...startup\ ***** .lnk

    The file may vary but its worth a look. The switches stand for -r (restart) and -t01 (restarts in 1 second).

    If they are there then delete the shortcuts and reboot. Other than this it may be a corrupted WINLOGON.EXE file and you will need to use Windows setup to repair your product.

    I hope this helps. Good luck!

    well I can assure you it is easier than it looks when you're there. But without the setup disc it's near on impossible to get to the recovery console. And with the safe mode problem it could be worse.

    In all honesty without that I am not really sure on what else there is to try. Oh, I have just noticed something. Ignore the last message, I should have read your post properly first!

    I have just noticed about the missing library. It seems like a vital system file may be missing or corrupt. Have you tried Last Known Good Configuration in the F8 menu? :)

    ok thanks anyway,last known good config works ok but its annoying to have to do that everytime i switch on,just thought i may be able to repair what is missing or corrupt,last known config it is then!!

    well normally when you choose that option you only have to do it once. That would sort it out once and for all. If not then you could always use that option and attempt to repair it from there. :D
