I recently got a Creative Recon3d PCIe. It's not working. When I start my computer, my sound works for 1 to 20 minutes. Then, the sound will suddenly stop. When the sound craps out, the youtube video I am watching will start to stutter (and of course I can not hear anything). Or if I was using winamp, then winamp cannot play songs.
Previously, I was using on board sound and had no problems.
Don't know how to solve your problem.
What i will say is that the majority of experienced soundcard members including myself never recommend Creative cards.
You have bigger issues with your cpu and mobo- obviously a typo(non-compatible)
