Was having crashes and graphic glitches when playing a game. Game trouble shooting suggested uninstalling present drivers and then updating video drivers to the most recent. Sounded reasonable.

I dl'd and installed latest AMD drivers for my gpu via the automatic detect function on their website. I also uninstalled the current drivers via device manager.

Device manager shows the uninstall was successful and then, after installing the new drivers, it again shows that the gpu is recognized.

PC will go through POST but hang at a green screen without fully booting. It will start fully in Safe mode. If I uninstall drivers it will fully boot. I tried a slightly older set of drivers from AMD with the same results.
I have tried System Restore to a point before I deleted the video drivers, no joy.

I'm kind of stumped now.
