Seems like only first posts in the thread are answered by microsft staff on this forum. Most of them are generic as I have discovered reading many of them. "Check your antivirus, third party software blah, blah. Check your Pm" and so on.
I'm afraid no one is investigating problem seriously. Been through this myself before: 780SLI chipset on asus deluxe board - problems with ever present blue screens, six or seven versions of bios, no support from asus (finally had to swap for evga). You have to see to believe how much hate can be poured on asus on what is basically official asus support forum :)
Then no support for midi/game port on creative audigy. Microsoft said its creative drivers, creative... well, didn't say much (left as is although windows keeps nagging me about unresolved problem).
Question is where to go. Have you got any ideas? I don't want to and don't have time to go to every hardware forum on the net crying about how bad microsoft is. And on most of them you would meet folks claiming they have resolved this issue by touching their left toe while keeping the power button on and scratching their empty memory banks or erase everything and start from the point blank.
