Check to make sure you are using the correct service pack (64-bit vs 32-bit).

Here is a Microsoft Readiness Tool for 64-bit SP1:

Here is the one for 32-bit:

Download and run the appropriate readiness tool. ... Thinkpads_User

I would start by installing the System Update Readiness Tool:
http://support.microsoft.com/kb/947821
And then try installing SP1 manually via "Clean Boot" state.
Download and save on your desktop: http://www.microsoft.com/download/en/details.aspx?id=5842
Remove your antivirus program
Click START and type msconfig in the "Search programs and files" box
In the new window, under the tab "General" click on "Selective startup"
Under "Selective startup" remove the check mark for "Load startuo times"
Now click on the "Services" tab and place a check mark in the "Hide all Microsoft services" and then click the "Disable all" button,
Now click OK and reboot.
Find and click the downloaded SP1 updated that you saved on your desktop.
When all is said and done and you need to get your PC back into a "Normal" start of state...
Click START > msconfig.
Under the General tab you simply put the click on "Normal "start and reboot.
