What is the exact error message with SP1?
Try installing Windows XP Service Pack 1a this way:
***PRINT THIS LIST***
Do not use Express Installation.
You can order Service Pack 1a CD from:
http://www.microsoft.com/windowsxp/pro/downloads/servicepacks/sp1/ordercd.asp
http://www.microsoft.com/uk/windowsxp/servicepacks/sp1.asp
Or:
The CD is also distributed with some magazines.
Or:
Download the Network Installation from here: (be sure to select the
correct language)
Also select "Windows XP Professional and Home Edition" Do NOT select
64 bit.

DSL takes about 20 minutes, if you do not have high speed access, get
a friend to D/L SP1a for you.
Then burn it to a CD and keep for the future.
It is best to resolve current issues BEFORE installing SP1a.
First check to make sure you have all updated drivers.
You should have at least 2gb free space (Less than half that is needed
for SP1a, but if you are that close, you need to start looking for
ways to free space or add another hard drive.)
Check with computer manufacturer to insure compatibility with SP1,
there are a few models where the company has said wait while the
manufacturer implements a fix.
Compaq and HP are 2 that I know of.
If you have HP or Compaq computer contact them before installing SP1a:

There may still be issues with the HP/Compaq fix, so you may want to
wait
If possible run Ad-Aware and delete spyware:

If you ever installed XP-Antispy, it disables a dll SP1a needs, so
just in case, Start - Run and run
regsvr32 licdll.dll
regsvr32 regwiz.dll
Run chkdsk to check file system.
Perform Disk Cleanup (all boxes checked except Compress old files)
Perform Disk Defragmentation.
Ensure correct date and time.
Disconnect all peripherals (camera, scanner, printer etc)
When you are ready:
Create a Restore Point in System Restore
Go to MSCONFIG, make note of what is checked in Start-Up tab then
uncheck all in Start-up tab.
Reboot the computer
Login as an Administrator, disable ALL unnecessary applications
including antivirus.
Do NOT touch any keys during the process unless necessary.
Install SP1a by double clicking on it, follow the prompts.
After SP1a install is completed, reboot, defrag.
Go back to MSCONFIG and recheck what you unchecked.
Then:
Be sure to check for other Critical Updates when finished.
