When i try to put on a video, it does matter what sort of file it is. The video player just show a black screen, but the audio works just fine. I've tried to install all sort of players / codecs / Drivers, but i still cant make it work. The graphic card is Geforce 7600Gs There is one way i can get it work and it's when i press Ctrl alt + del when it's playing the "black screen", then i close the player with much lagg. If im lucky it works next time i open the file in the player, otherwise computer restart or just same as before. I know it works cause i did just reinstall windows the otherday and it did work fine for a while, until i installed some programs, then it didnt work again. I did uninstall all programs, and suddenly it did work again. Then i did reboot my computer, and it didnt work again . i uninstalled all programs that i thought could be a problem, but it still doesnt work. If someone got any ideas what it is please tell. Please help meee!
