I searched and did not find this problem listed anywhere. I consider myself pretty pc savvy but this has got me stumped. Anytime I load media player or any video player (Nero etc) my computer all but locks up. It slows down to almost stopping and all the icons begin to flash on and off. I have to "hard dump” it to refresh. I’ve tried updating video drivers ,reinstalling WMP . I am running windows XP Service pack 2. I also tried dxdiag didn’t find a thing. Running bit defender it did not find any viruses. Any help would be appreciated.
