I am at a loss. Since acquiring Windows 7, most UTube music is muted; sometimes the music is great the vocals are slurred and muted. MSN games operate, but only to a certain level, then they freeze. I run Pandora; the sounds is garbled, even after downloading Pandora Gadget. Email freezes if there are more than 5 emails in the inbox. It seems there is no way to contact Microsoft to complain of these problems. Would it help if I downloaded the compatible XP version? (XP was great, windows 7 sucks).
Most likely it's not a problem with Windows itself, but more likely drivers. Do you have proper drivers for all your devices?
