HELP!!! SYSTEM CRASHES.....EVERY Night

[Azkaraoke4]

I had a problem with my computer crashing and giving me problems that I couldn't figure out. Not nessesarily loading peoples disks but just whenever it decided to. I narrowed it down to the sound card I was using. I was using the audigy external ummm.... NX I believe. This was on a regular pc mind you but I was still using an external. So I bought a 29.00 internal sound blaster, loaded the correct software and havn't had the problem since. Maybe this could help. Oh by the way does anyone know if you still have to turn down the hardware acceleration on the sound cards or is that problem taken care of?
