nightthief Posted April 20, 2007 Share Posted April 20, 2007 Neo,Deleting all the files in the aforementioned directory and then rerunnning the Self Assessment Test is precisely how I fixed this on my own system.Since this does not work for you, the first place I would check is your video-card drivers. Both ATI and nVidia have released new drivers on their webpages which claim to correct bugs in the Assessment test - with ATI's old problem being the worst since it crashed the test. Download the new drivers, uninstall your current ones, and then install the new set. Link to comment Share on other sites More sharing options...

nightthief Posted April 22, 2007 Share Posted April 22, 2007 That is strange. I just updated my own system to the 7.4's, deleted the files in the Windows\Performance\WinSAT\DataStore folder and reran the assessment without any problems. Do you have User Account Control turned on, by any chance? If so, Vista would not have actually deleted the files in the Datastore folder for you, but mirrored the deletion using your user data folders. Check to make certain UAC is turned off before you delete the files and run the assessment. Link to comment Share on other sites More sharing options...
