One of them is (hopefully) easy to fix - so let's do that first....


Close all open windows.
Open an Elevated Command Prompt window, and type the following command

wusa /uninstall /kb:971033

and hit the Enter key
Accept the warnings/confirmations, and wait for it to complete

copy and paste the output (if any) from the command prompt window to a reply here,
Reboot

reinstall the update from http://support.microsoft.com/kb/971033
Reboot

run an MGADiag report, and post it.
we need to see a full copy of the report produced by the MGADiag tool
(download and save to desktop - http://go.microsoft.com/fwlink/?linkid=52012 )
Once saved, run the tool.
Click on the Continue button, which will produce the report.
To copy the report to your response, click on the Copy button in the tool (ignore any error messages at this point), and then paste (using either r-click/Paste, or Ctrl+V ) into your response.

How many Language MUI packs do you have installed? (do you need them all?)
What is the base language of the system?
