No sound, no sound device detected, drives installed?

[Madtheos]

Hello there! So.. I'm in a pickle with my machine and Windows 7 after this latest update. On startup I get an error from MMDevApi.dll saying that it might not run on Windows or... something else. This also occurs anytime a program tries to use the sound card ie. WoW, Yahoo IM, Live IM, SL, etc. I've updated my sound card drivers to the newest ones. I still get an error that says the device is detected when going to "Sound Devices" in the control panel.

Trying to adjust the sounds themselves leads me to the Windows Audio thing... which won't start even from the component list.

Sound Card is a SB Audigy SE

I have a similar fault with SB Xtreem Music - downloading the latest driver (2.18.0013) sems to corrupt Windows Audio file and it also prevents me from accessing the Control Panel, do you have this fault? otherwise sound is ok.
