Advantage Validation shutdown loop

[bev3561]

Hi My laptop is on a start/ shutdown loop, it has got an installation box with Advantage Validation, I cannot click next, or cancel, the laptop shows a small blue box with error message and closes down straight away before I can do anything??? Can you help please?

Do you have a valid Windows CD Key?

Had a few false positives myself. Boot into Safemode and run this - Reset Windows Genuine Advantage Validation
