I can't run the Windows Experience Index after performing some hardware changes. Since two weeks ago when I first had the issue, I have tried rebooting, upgrading the SSD, and upgrading the graphics card. I have also done a search on Google.

After installing an SSD then optimizing the system for proper performance, I was unable to complete the WEI evaluation. I re-enabled indexing and the WEI completed with no problem. Sorry, but don't know if that was a fluke or even if that's what really allowed the completion of WEI although my feeling is that indexing being disabled was somehow interfering.
