What does the error log say?

Here's is Microsoft's fix:

• 1. Click Start, click Run, type cmd.exe, and then click OK.
• 2. At the command prompt, type cd %SystemRoot%\system32\dxxpdbg, and then press ENTER.
  Note In this command, %SystemRoot% represents the folder that contains the operating system files.
• 3. At the command prompt, type dxxpunp.exe, and then press ENTER.
• 4. At the command prompt, type exit, and then press ENTER to close the command prompt.
