For the last three weeks, after the weekly Windows 7 update, I get an error message that the AMD driver is missing or malfunctioning. I have an HP i7 Envy notebook with an AMD video card working with Intel driver. The Intel and AMD drivers show exclamation points next to them. I tried installing updated drivers to no avail. Only thing that has worked is doing a system restore to before the update, but do not feel that this is the best way to move on.
