Hi All
For info - all this hassle with slowing pc and video/sound drivers seemed to start just after the March W7 updates - my system was set to auto update, now disabled - this included Silverlight, then after the first issues I installed SP1 (after I searched, it was not presented automatically).
So lots of virus and other work in and out of safe mode, unistall and reinstall drivers etc, Conexant HD and mic still playing up, poor sound levels and crashing mic set up.
Well I hope I am not tempting fate (really sooo do)- late last night I unistalled SP1 (pc seemed immediately better) and then all except the security update from 8/3, including uninstalling silverlight.
immediately the PC seems to be fater, less CPU usage and memory use, less HDD activity AND...I ran one mic set up test and it worked (well it did not crash and said it was complete when it should do).
I will run more checks etc, but I am hopeing that I have found the culprit! - damn MS Silverlight (whatever that is) and/or W7 SP1 or other updates from begining of March 2011 having compatibility issues with conexant HD drivers (4.98) and (maybe) ATI HD graphics drivers (though updated driver
from their website -won't do it via 'update' button- seemed to fix it) and these MS installs generally killing your system. (note as above conexant don't do updates to 'counteract' the silverlight and sp1)
If you have conexant HD mic issues, try seeing if you recently installed Silverlight or SP1 (in windows update history) select them and unistall (can alwasy re-add later very easily).
I have everything crossed
Anyone know if this has been advised or MS have heard it?
