After an update of XP home towards XP pro SP3, my pc freezes on a blue screen with the focus and without error message at request of validation. What is the problem? I tried several solutions of Microsoft without succés.
In order to receive the best support, we request all users initially download and run the Genuine Diagnostics tool (MGADiag.exe) at this link http://go.microsoft.com/fwlink/?linkid=52012. Click "Continue", click the “Windows” tab, and click the "Copy" button then “Paste” the report into a reply message in this thread.
Also, I am unsure if I understood you, your computer gives a Blue Screen error when you attempt to Validate. Is that correct?
