I have a problem with video files and also copying and pasting from the clipbook. Running XP Pro on an Athlon 1200. Using a Maxi Gamer Cougar 3D card driven by NVidea 28.32 detonators. Any attempt to open an mpeg or an avi brings on the BSOD. Sometimes, opening an office file with an embedded graphic brings the same result. Recently installed Office XP Pro but this has introduced the exciting new variation of not allowing copy and paste of image files - haven't tried all of the formats yet, I'm getting fed up rebooting. Any help anybody?
