Well, I've tried basically every driver and still getting the same clicking sounds whenever I run an internet browser, or move the mouse to much, or open the volume panel, or anything along those lines. I installed the unit onto my friends PC and he ran into the same problems. This happens from multiple sources (foobar, winamp, youtube) and with all 3 outputs (both headphones jacks and the red/white out). However, as soon as I start running ANY game (WoW, MW2, TF2, LoL, SC2) the clicking STOPS. I can't figure it out for the life of me.
The only thing I haven't tried yet is changing my multiplier in my BIOS settings to not underclock my CPU. My Mobo will drop my system multiplier to 6x from 9x when not under load. Do you think when the system changes back to 9x from 6x for a split second under small load (opening a browser) that it might be the source of the clicking? That's the only thing I can come up with.
