I've got a Dell Dimension 4600 and recently needed to clean everything out due to viruses. Since the reboot, the computer has returned to functioning at its naturally high level, however, I haven't been able to access any audio. The audio section on the Control Panel is all ghosted, saying there are no audio devices available. I've used my CDs Dell provided in case we needed to reinstall any hardware, but every time I try to install I get the error message that reads: "Error installing iKernel.exe:(0x10000)". The install the failed at that point and no changes were made, even after restarting the computer.

Any suggestions on how I get around this and start hearing again?
