I have an Athlon 600 on a GA-I7X motherboard, 256 meg mem, 52x true speed cd, voodoo 3 3000, mmx 300 sound card, zoltex modem, pci lan card, problem is whenever i play a game with sound it will lock up, if its demanding sound ie freespace 2 with arual 3d on, it locks up in about 2 minutes, if i lower the sound level it takes longer, ie i can play heretic 2 for about 3 hours on low sound quality before it freezes, i have no conflicts, went out purchased 2 diffrent sound cards, made no difference, if i alter the memory setting in the bios i can have my computer last longer before freezing but it will still freeze, i can play the cd using cd player all night however and the computer will not freeze, if im not using sound, ie web browsing/downloading the computer will not freeze, i am all out of ideas please help
