Background: Haven't installed anything new recently. Started noticing problems while playing an online PC Game right after one of their updates. Little hiccups here and there (freezes), but big troubles when accessing one specific part of the game (complete crash: "ialmrnt5 display driver" error message leading to manual restart via ye-olde plug in the wall). I mention this because the game employs the less-than stellar "GameGuard" Anti-Hack Program, and I've heard other people complain that it has wonked out their drivers/various stuff as well.
Anyways; I tried updating the drivers to no avail, then tried to tweak some in-game settings to see if that would help. Of course, the game crashed and upon restart/checking through the Device Manager I got:
"The drivers for this device are not installed. (Code 28)
To reinstall the drivers for this device, click Reinstall Driver."
But reinstalling won't work. It will go through the motions and fill the progress bar, but ultimately fail ("Access is Denied"). Good peoples of Geeks to Go: Any help?
