beeping and lagging under heavy button pushing keyclone

I am playing a 5x frost DK team, and it doesnt happen a whole lot, but sometimes when I'm in heavy battle situations, I'm getting a bunch of beeping and lagging from the normal speakers I use. Not fro mthe internal cpu speaker. It seems like the computer is remembering every button push I do, and trying to execute them all before moving on. sometimes when I stop pushing buttons when it happens, the last 8-10 commands I gave still try to be performed. I am using windows 7, and keyclone. I never experienced this problem when I was using Win XP, or keyclone on other computers I have used. Any suggestions on whats causing it, or how to fixit?
Thanks

What kind of computer are you running everything on? we'll need some actual information about your setup before we can even do more than guess what your problem is.

Computer setup:
Intel i7-870
Asus Motherboard
Windows 7 home
GTX460 Video card
8Gb ram
WoW and Windows running on 80gb Intel SSD.
All other programs on 1Tb 7800 rpm Seagate hard drive. I dont run things in the background when playing. No music or videos.
What else?

I did a quick google search and saw mention of keyboard buffer being full and Sticky Keys getting turned on as 2 things that will cause beeping. You might also be dealing with a stuck key {as opposed to Sticky Keys} if you use the Strict option in Keyclone.
