Don\'t post the same question twice. If a mod comes on, they will move it to the appropriate forum.
Anyway, run the program \"pssetup.exe\" to set the resolution and color depth to lowest, and also try \"software mode\" (it may help)
Anything that you might have installed in the meantime might have corrupted some part of windoze, maybe the directx or graphics drivers, which might be the reason. Otherwise, you might try to reboot to get windoze back into some working shape. Also, make sure that you have enough swap space (at least 200 MB) and 200 MB of RAM. Also close all other programs that might be running, as PB needs lots of memory.
Edit: The failure messages aren\'t of any importance, they\'re normal (there will be four of them). However, the \"alternate driver\" message doesn\'t appear on my system, therefore there might be some problem with your graphics drivers despite it having worked once, maybe corruption by installation of ned software (games) or driver updates.
