SP2 causes errors and instability

B

Hello,

I've been working on a Dell Dimension 4400 for several days. Initially
the computer had a spyware infection. While cleaning it up I got a
message telling me some windows files had been changed and i needed to
insert the Windows XP CD to restore them. Didn't have CD handy at the
time, so I installed SP2 hoping it would replace the corrupt files.


Soon afterwards I got a message on reboot saying Windows had recovered
from a corrupt registry. I was going to do a SFC /scannow, but at some
point I was no longer able to boot into Windows.


I did a repair install at the 2nd prompt. Later when reinstalling SP2,
the installation failed somewhere, and Windows automatically removed a
portion of SP2. This condition was totally unstable.


Next, I did a quick reformat and fresh install. Everything seemed
better until the old message came back, "Windows recovered from a
corrupt registry..." on a reboot after installing SP2 or one of the
other critical updates. Soon I was no longer able to log on to Windows
at all...no user names appeared in the logon screen...hit CTRL + ALT +
DEL twice and the old Windows 2000 style logon box appeared, but
Windows refused to let me logon under Administrator or the user name I
set up with blank passwords.


I ran the Maxtor Diagnostics test from floppy, and it found no problems
with the hard drive. I ran Windows Memory Diagnostics all night, but
it found no errors.

Next, I did a complete reformat and reinstall with no problems.

Ran Windows Update. First update installed 2 updates (Windows Installer
3.1 and one other)

Restarted successfully.


Ran Windows Update again. Installed 25 updates.

Restarted successfully.

Ran Windows Update again. Installed SP2.

Restarted, but system spontaneously rebooted before usual screen
appeared to enable automatic updates.

Ran Windows Update. 5 updates installed.

Restarted, but blue screen of death appeared briefly, and system
rebooted. Low screen resolution prompt after reboot.

Uninstalled SP2 and 5 last updates. System was stable again.

Downloaded and installed SP2 for IT Professionals from Microsoft
download site.

On reboot got message "A problem is preventing Windows from accurately
checking the license for this computer...."

Rebooted in Safe Mode, and uninstalled SP2.

What can I do to get SP2 to work on this computer?

Thanks in advance.

Bill
