I just bought an 8800 GT for my MP, it runs well and everything except for a weird buzzing coming from my speakers on my monitor (HP f2105). It only happens when I am running WoW in OSX, or when I play any graphic intense games on my XP partition. It "buzzes" continuously, even when I mute the sound. I'm not quite sure what I should be trying to do, or even if the two problems are related. Any help would be appreciated, thanks!
