Here's a quick solution to try before reading through the other steps:
  1.. Start the Administrative Tools utility in Control Panel.
  2.. Double-click Services.
  3.. Right-click Cryptographic Services, and then click Properties.
  4.. Click Automatic for Startup type, and then click Start.

If that doesn't work, then grab a soda and get ready for some fun. ;-)

1. Try the resolutions in this recently released MS article:

2.  Save and then Open the "DX9 Logo Error" patch on Line 189
     for WinXP at: http://www.kellys-korner-xp.com/xp_tweaks.htm

3. Repairing Windows is our final option.  Boot from your Windows
    CD (you may have to press F12 while starting up, or change the
     bootup order in your BIOS) and then follow the instructions at:
