i just redid my system. followed the basic rules for reinstalling. not that it is hard everything runs great, fast as hell but one big delema when ever i play a video no matter the size. the video leggs to like 5fps. but only when i use the menu system or a bubble tip or something like that pops up. i have the most current nvidia drivers for my computer. all games are ok. no other media is effected. every video format is affected. and it all works fine on other computers. anyone have any ideas?
