Windows 7 64-bit Distortion and Audio Bug is Major Problem

What's going on with this Windows 7 64bit bug that I and thousands of others are experiencing with little or no solution to be found?

If you're running the OS, you know what I'm talking about. The staccato audio distortions with a laggy mouse and peripherals. You play with the sound settings, check to see if you're running out of available RAM, but your DPC Latency Checker is showing MASSIVE spikes nonetheless.

I've been doing a lot of searching on the subject lately but still haven't solved the problem. A lot of what I've found says it's related to IRQ, but in my Zotac system there's not a lot of hardware reconfiguring I can do. I've got BIOS options for it, but to be honest I don't know where to start.

Here's some of the threads of similar problems I've found in my searching:

Microsoft, please address this problem. This is unacceptable for an OS that's been in the general marketplace for so long.  This is a core problem and even if you can't fix it, please let us know.
