During the setup of ALCOHOL 120, my PC suddenly rebooted and I noticed that from this moment on, I got a YELLOW EXCLAMATION MARKER near PLUG AND PLAY BIOS EXTENSION in DEVICE MANAGER. It says "Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)". I tried some PLUG AND PLAY devices (Camera, Scanner on USB) and they seem to work, but I got some problems with my video card. It's impossible to activate HARDWARE ACCELERATION in DivX Player and other software.
I tried to update the BIOS which worked but didn't solve the problem.
I've got an ASUS PVP800 Deluxe Motherboard, Windows XP PRO SP2, RADEON 9700 PRO.
