The Blue Screen notice is : machine_check_exception which I believe is a registry problem and the fix would be to run a registry fix..

the work I was doing on this PC prior to the blues screen was to remove virus/malware program called Webroot , thru the control panel , turned off IE , & google chrome - installed Firefox browser, turned off or removed Microsoft essentials, and installed AVG free software ..

windows vista no longer has support for IE,, or chrome ,, or essentials .. thought it best to remove ..

so for the windows fix is there a Microsoft based program for this . really don't wan tto purchase any third party software for a registry fix ..
what about sfc /scannow ? I don't have the CD for any missing drivers ..
