kmixer.sys problems

[Jamess B. Holladay]

Can any one shed any light on "kmixer.sys" what it does and what can cause
it to crash a computer? Is it a necessary file and if deleted will it
restore its self to a good file?

Why don't you check with that file's properties:

| Kernel Mode Audio Mixer

and what can cause it to crash a computer?

That depends on the circumstances when that crash occurs.

Is it a necessary file
Yes.

and if deleted will it restore its self to a good file?

That depends. Install this optional update in order to fix
some problems: http://support.microsoft.com/kb/920872/en-us

"kmixer.sys" has the version "5.1.2600.2929" when done.
