I have a custom built pc that my friend put together for me. This also has a sound card problem - The sound stops working after a sound has been played more than a couple of times, and the computer might freeze or restart after a while. I know this is the sound card/driver because the computer works fine when i disable the driver. I meant to use this computer for multimedia so i have an asus motherboard with an external echo event gina 20 sound card. I have tried downloading an re-installing the driver but that doesnt work. I'm guessing something must be configured wrongly, or the driver isnt compatible for some reason.
