Graphics/Sound Stutter > WIN7 Freeze>CRASH

[neo101]

Ok MSoft - I don't know if this has been posted/well known. Might have found a bug!

Please divert this post to Sound or Graphics area of website if needed!

I was using a spare Nvidia 6200 512mb Card (which runs Aero etc fine!) I can't get the Win 7 performance thingie to work as it keeps crashing at video.
(That's despite me able to watch DVD films perfectly on my internal blu-ray player and did a test race with huge game GTR EVOLUTION which ran perfectly on my fanless 6200 card (just for a laugh )

Anyway went to change "Video Aperture" from Bios default 64 to 128mb.

This caused 3d graphics/3d screensaver crash, music stuttering, UTUBE video stuttering/crash, Media centre music stuttering/crash.
This is repeatable!

I think this is conflicting with the Realtec sound driver poss in memory!
Is this known about?

I have seen many people posting about this on the internet.
Thanks for any solution.

I solved my own problem after a hunch and delving into WIN7 software nether regions.

Had a look in:
device manager > system devices > [Nvidia nforce2 AGP HOST to Pci BRIDGE]

Found 3 instances of the driver.
I updated to most recent version I could find and 'hey presto' all sound and graphics now working at full steam > 100%
NO MORE CRASHES OR VIDEO/MUSIC STUTTERING!

Can now also update Graphics 'aperture memory' in bios to any setting I choose without a problem!

Windows 7 'Performance Indicator' (W.E.I.) now completes without a hitch too!

Hope that helps some of you out there!
