HIS Radeon HD 3850 Causing High CPU usage

[Guest]

Greetings guys. this thread is the one that busted the problem wide open for me. i suffered from high cpu usage that taskmanager could not attribute to any process, like many here. i undertook the AA twelve step process to recovery and...

owait, wrong fix. rite, about that then.

seriously, i recalled that when i installed the drivers for my Visiontek HD 2600 AGP graphics card, it also installed this 'Microsoft UAA Bus Driver for High Definition Audio'. finally locating and disabling this device in the device manager under 'System devices' fixed my problem immediately. i will note that my card in fact has no audio capabilities whatsoever. only two dvi ports and a svideo port. no audio at all, which might be the problem. maybe the driver is trying to access hardware that is not there. i don't know.

in any case, problem solved for me, on my winxp pro, sp3 machine.

thanks for the help, folks.

Thanks a lot, it solved my problem too.

I can't be sure that the issue is with the drivers installation or with windows that adds that device 'Microsoft UAA Bus Driver for High Definition Audio' as soon as it detects the new card. I say this because i noticed that the drivers installation was very slow since the beginning. And uninstalling the drivers doesn't solve it.

Anyway, the solution is the same, just disable the device in device manager.

I installed an ATI AH3450 AGP 512MB, my old GT6600 more often than not wouldn't start and it was taking me sometimes more than 5 on and off cycles to finally get some image and get the pc started.

Note: disabling the ATI audio device didn't work for me, but this device was gone after disabling the Microsoft one.

I have same problem in my HD3650 AGP, I try the following two step, and success.
1.disabled all port not in using, as LPT,com1,com2,etc.
2. CHANGE your computer driver from "ACPI ...PC" to :"Advanced Configuration and Power.." and reboot PC.

Hi, can you please detail a little bit the procedure, exactly where did you disable these ports and how you change the computer driver ...
Thanks

Wow! I was wondering why one of my 8 "cores" of my new i7 920 system ( http://www.htmlvalidator.com/CSEForum/viewtopic.php?f=6&t=753 ) was running high CPU usage. I disabled all three of my "High Definition Audio Controllers" in the "System devices" and it fixed it! Running Windows 7 x64.

But then I had no audio. I enabled one of them (the one that didn't seem to be related to the two ATI video cards I had in the system) and my sound came back but my CPU usage didn't.
