Hi All, recent graduate from WinXP X64 to vistax86 business (yes i did the upgrade :thumbsup:; not clean install)

OK i have noticed that task manager reports svchost.exe using upwards of 100K memory at idle. This seems a bit odd to me. I have only installed afew apps since upgrading.
I have SP1 and all windows updates installed.
System Specs:
AMD 4400+ dual core
MSI K8N daimond+
2GB Corsair PC3200, dual channel
2X fuji 160GB SATA HDD RAID0 on nvidia RIAD
2X Nvidia Geforce7900 GTO Sli


Avira Antivir recently detected TR/Gental.2176, but i deleted on first occurance.
reran Antivir and no detections.
I ran stinger and spybot S&D- no problems found.

ran HJT( 1st time i ever used this)
here is my logfile:

So, Back to the original question:
Why is svchost.exe using so much memory? all the information i can find on the web states svchost.exe should only use 10-5=30K of memory. Do i have a problem?
Thaks for any help

OK, i found this out:
I killed the process in taskmanager and lost sound.
Am using onboard SB audigy sound chip on the mainboard.
so vista asked me if i wanted to retart sound services and i did, sound works, and svchost.exe is not running any instances above 14K memory usage.

the svchost process from process explorer was using P17RunE.dll (before I ended it in taskmanager above)which is the creative sound .dll for sound.
I installed vista x86 because MSI mobo website stated no support for raid or onboard SB audigy in vista 64-bit OS for my motherboard.

this leads me to believe some kind of memory leak in the SB audigy drivers? but what can i do to stop this?
Anyone have any thoughts?

Thanks again:)

Hello. I am PropagandaPanda (Panda or PP for short), and I will be helping you with your log.

I apologize for the delay in response. We get overwhelmed with logs at times, but we are trying our best to keep up. If you have since resolved the original problem you were having, we would appreciate you letting us know. If you still need help, post a new HijackThis log.

Further more, you should not be taking any advice relating to this computer from any other source throughout the course of this fix.
