IRQL Not Less Than Or Equal

I keep getting this error after I recently updated my nvidia driver. Its happened 3 times in 3 days now and I can't seem to find out why. I've tried uninstalling the new driver and reinstalling the previous one when it was working fine but it didn't help. That's when it crashed for the third time. I have attached all the dmp files from all 3 crashes. Can someone help me please?

System Spec:
Q6600
260 GTX C216
W7 x64 Ultimate
2x2GB G.Skill DDR2

First dump file blames ACPI.sys - a component of the Windows operating system.
The next 2 dump files blame cmudax3.sys - a component of your C-Media Audio Driver (WDM)
Please download a fresh copy of the driver from here: C-Media Electronics, Inc.
Then uninstall the current C-Media Audio program from your system - and then install the freshly downloaded drivers.
