On my Dell there was a setting in the BIOS to turn the onboard sound on or off. No other settings, just on and off. As Basher suggested maybe there is a BIOS update you could do as well. I suppose you could also temporarily remove your other sound card and try the on board sound to see if the problem disappears. This may help to identify if it is a hardware issue anyway.Yea theres a sound card built into the motherboard and I've navigated through the BIOS settings and there arent many options to edit so how would I go about turning off the on board sound through the BIOS?? The only way I've tried disabling it is through the playback devices list in the control panel>sound menu.. Thanks
Good luck getting this resolved. I gave up on my system after replacing every component including the motherboard and Power Supply. So I foolishly went out and bought a new computer. An HP HPE-150f running Windows 7 x64. Guess what? Exactly the same problem. The only common factor is Windows 7 x64. The only workaround is to reboot the computer several times a day.
Thanks kemical!
I'm puzzled by the NVIDIA\Realtek label also but that's how it was identified by PCPitstop's overdrive scan, and Device Manager shows exactly the same thing:
NVIDIA High Definition Audio
NVIDIA High Definition Audio
NVIDIA High Definition Audio
NVIDIA High Definition Audio
Realtek Realtek High Definition Audio
I do have the latest Realtek drivers installed, and I think I have the latest NVIDIA drivers installed (for video), but I'm not really sure what the "NVIDIA High Definition Audio" device is. I'm assuming it's an onboard chip related to the realtek device.
I Looked at the CD that came with the MoBo and the only mention of Audio Driver is the Realtek HD Audio Driver v5.10.0.5745. No mention of anything NVIDIA at all. I tried deleing the NVIDIA High Definition Audio items but they just reappear at next boot. I tried disabling them, but that had no affect at all on the system or the problem.
Beffuddled!!!
