Help! Startup automatically reboots halfway through

I'm not too sure why, but every time i start my windows
2000 pro computer, it reboots itself after about half the
setup process (straight after when the coloured screen
with the windows 2000 pro logo and blue progress bar
disappears). Then a blue screen with some writing comes
on for about half a second and it reboots. I've tried to
setup in safe mode but it reboots itself even earlier!
(Straight after the first setup screen with the white
progress bar). I'm not totally sure why it happens but it
may be because of this:

About a month ago, I installed loads of windows hotfixes-
more than what windows automatic update suggested to
install, so recently, because it was slowing my computer
down, I tried to uninstall them all and reinstall them
according to what windows automatic update suggests.
While I was uninstalling the hotfixes, I had to reboot my
computer after uninstalling some hotfixes. I got fed up
after a while and ended the "finish by restarting
computer" dialog box with task manager so I wouldn't have
to reboot so often. After uninstalling a particular
hotfix, I forgot to use the task manager so the machine
rebooted as usual, but rebooted itself halfway through
setup, and has been stuck like this. The hotfixes I have
uninstalled are:

If it is not due to this I have no idea why it happening
as I have used all the other programs in my computer for
a while without my computer breaking. Please HELP!

Thanks
 
Well, I can offer a few suggestions that might help:

First is to roll back the registry back to its previous state (or the date
of the back-up hives):

http://support.microsoft.com/default.aspx?kbid=307545

To complete part one, follow these steps:
Insert the Windows XP startup disk into the floppy disk drive, or insert
the Windows XP CD-ROM or Windows 2000 CD-ROM into the CD-ROM drive, and
then restart the computer.
Click to select any options that are required to start the computer from
the CD-ROM drive if you are prompted to do so.
When the "Welcome to Setup" screen appears, press R to start the Recovery
Console.
If you have a dual-boot or multiple-boot computer, select the installation
that you want to access from the Recovery Console.
When you are prompted to do so, type the Administrator password. If the
administrator password is blank, just press ENTER.
At the Recovery Console command prompt, type the following lines, pressing
ENTER after you type each line:

md tmp

copy c:\winnt\system32\config\system c:\winnt\tmp\system.bak
copy c:\winnt\system32\config\software c:\winnt\tmp\software.bak
copy c:\winnt\system32\config\sam c:\winnt\tmp\sam.bak
copy c:\winnt\system32\config\security c:\winnt\tmp\security.bak
copy c:\winnt\system32\config\default c:\winnt\tmp\default.bak

delete c:\winnt\system32\config\system
delete c:\winnt\system32\config\software
delete c:\winnt\system32\config\sam
delete c:\winnt\system32\config\security
delete c:\winnt\system32\config\default

copy c:\winnt\repair\system c:\winnt\system32\config\system
copy c:\winnt\repair\software c:\winnt\system32\config\software
copy c:\winnt\repair\sam c:\winnt\system32\config\sam
copy c:\winnt\repair\security c:\winnt\system32\config\security
copy c:\winnt\repair\default c:\winnt\system32\config\default


Type exit to quit Recovery Console. Your computer will restart.

Note: This procedure assumes that Windows is installed to the C:\Winnt
folder. Make sure to change C:\Winnt to the appropriate windows_folder if
it is a different location.

If this allows you to boot up then I suggest that you then go back and one
by one start putting your registry hives back in use from back-up till you
find the one that is corrupt.

I would start with the system then software then doesn't matter where you
go from there.

If your system continues to reboot after replacing the registry with
back-up I suggest an in place upgrade. It will not affect any current
programs just rollback the system files to the install level of the CD.
You will need to patch your system back up to the current Service Pack and
Hotfix levels. Below is the link with instructions for an in place upgrade:


http://support.microsoft.com/default.aspx?scid=KB;[LN];315341

If this does not fix your issue I suggest that you do a parallel install
(preferably) to another partition but, you can use the same partition just
rename the system folder to something besides windows or winnt. This will
allow you to see your original installation and access data as needed from
the Hard Drive. The link below has the instructions for a parallel install:

http://support.microsoft.com/?kbid=266465

However, if you are still trying to get your original O/S up and running I
can offer you a few more steps:

First, make a folder in your original install c:\winnt\system32 called
backups. Now highlight all the FILES in the ROOT of the c:\winnt\system32
folder and MOVE them to the backup folder. IT IS VERY IMPORTANT TO GET
ALL THE FILES AND FILES ONLY. Now you should have no files at the root of
your c:\winnt\system32 folder. OK, go to your parallel install
c:\%sysvol%\system32 and copy all the files from the ROOT of the directory
to the c:\winnt\system32 folder. Once you are done you can try and reboot
into the original install and see if it lets you in.

It may error out asking about a driver if so follow the steps below:

Boot to your parallel install. From here go to c:\winnt\system32 and
RENAME the drivers folder to driversold. Next copy the drivers folder from
c:\%sysvol%\system32 to c:\winnt\system32 and reboot.

I hope this helps and have a nice day!
