i have this evga geforce fx 5700le 256mb 128bit viv card and it likes to lock up at times. my screen freeze's and my sound skips repeatedly. i play c.o.h (city of hero's ) and sometime's everquest (i play c.o.h more ) any idea's about this. and i have a soundblaster 5.1 live digital sur. card. it would do it alot with that card i am curently useing a 4.1 sound blaster card and it still dose it.
