Hey Guys,

I have done a clean install of XP and updated all the necessaries (SP3)
It was running very slowly and with the help of Process Explorer (great utility IMHO) found:

Microsoft UAA Bus Driver for High Definition Audio was hogging 80-90% of my CPU!!

When I disable it, my CPU usage dives to near 0% and everything is fine!
The probablem is that even if I uninstall it, windows reinstalls it at next bootup, so i have to go in again and disable it!!
Anyone got any bright ideas? I'm stumped.....

cheers,
dorky

Why not uninstall it?

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

After installing the OS did you download and install the correct chipset driver?

Hey guys,


Thanks for the responses!

dc3- this is the whole problem. If i disable it, at next reboot, windows re-enables it.
If i disable it and uninstall it, at next reboot, windows auto-detects a new device and installs the driver automatically!

Allan - i'm pretty sure i did, but i am going to recheck right now. Finding those drivers is daunting!

How are you disabling it? In the Task Manager or msconfig?

One thing you can try is to turn off the lower-pane view. It seems that there are a number of topics suggesting that this is causing high PCU usage.

Personally, I would just uninstall it since the only time you need it is to see what processes are running that aren't being displayed in Processes in the Task Manager.

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

update:

allan - double rechecked chipset drivers and they are up to date!

dc3 - I am disabling/uninstalling in computer management> system tools> device manager>system devices >
then right click on "MS UAA Bus Driver..." then click: uninstall/disable
This works and cpu usage goes from 95% down to 2% (process explorer verified)
but at reboot, the driver is auto-installed and enabled!
I could live with it and just disable at every reboot, but theoretically shouldnt there be a proper fix??

When you disable it in the Device Manger and restart your computer the New Hardware Wizard will reinstall the drivers, this its function. Try disabling it from the startup list in msconfig.

Start> Run, type in msconfig and then press enter. Click on the Startup tab and scroll down to Process Explorer and remove the check mark from the box. You will still be able to use the program, it just won't start until you want it to.

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

Allan,

I think you're on to something
From what i have read, it seems to be a problem with my ATI video card software not liking a Sound driver??
I'll email ATI (AMD) and see what they say!!

cheers

Based on what I've read elsewhere your problem is not unique and yes, I would either visit the ATI support forum or contact them directly.
