I have a problem. I was cleaning out my pc by uninstalling some unwanted programs. I accidentally uninstalled something that was needed. Now whenever i try to boot up my pc, it automatically restarts after the windows 2000 pro startup screen. I cannot even get to the login screen. Help please. lots of info on this machine.

Do you have the Win 2000 CD? If so, go into the BIOS and set the boot sequence to CDROM first, put the Win 2000 CD in and reboot. When setup starts, it will give you the option to repair existing installation, choose that. Just a side note: Even if you could not get your system to boot up, your data would still be retrievable by removing your hard drive and hooking it up as a slave on another working PC. If the file system on your Win 2000 hard drive is NTFS, you would not be able to put it into a Win 95 or 98 PC, because they won't recognize the file system. Good Luck raincheck

OK, i tried that. Still no luck.

repair win2k installation set your bios to boot from cd and use your win2k disk to repair installation.. you'll keep all youyr files but may need to install your drivers and settings again

I have same the problem, on my other computer, where it has happened twice. I don't what causes it (any ideas or solutions would be appreciated)but I came to the conclusion that the only way to get round this without reformatting the harddrive is to, as suggested above, use the set-up function on the Win2k disk, but the repair function seems ineffectual. Instead you have to re-install windows 2000 for it to have any effect. The advantage is that it will get your pc working again with all of your old files but many programs don't function, and need to be re-installed as the registry has been completely changed. If there are any alternate solutions or suggestions as to why this happens, or how the files get corrupted please let me know so I can try to avoid doing so in the future. Thanks ps. I seem to have been using alcohol 120% programs on both occasions prior to my last functional shutdown, could this be anything to do with it?

If instead of choosing repair, and choose install instead. will all of my programs not work? and what about email-outlook express. will i loose all of those emails?

Did you try hitting F8 and booting into safe mode? or last known good ? I had this problem at work as well, in the BIOS I tuned on the BIOS option ACPI, it's some power option...
