Try to give some examples.
My former daw - an xp machine - I got pops in audio just opening a popup menu in daw, Sonar at the time.
So unchecking a simple thing like background shadow on menu - fixed that.
So certain visual effects occupy busses some, it seems.
At least on windows 7 there are some general settings you can try - optmize for visuals, or optimize for performance - just as a test to see what makes a difference. Then you can go into details and try every option what matters.
And if WLAN adapter those are known to cause some of what you describe. So wireless network, do cables instead.
