Ok /tek/ I have a huge problem...

On occasion I will get a problem, mostly common when playing games on my computer. Where a large tearing sound will occur from the speakers and the cursor will begin moving fun when im operating it. The cursor seems to move at 1-2 frames, meaning I issue it to move half way across the screen and I may see it move in 3 sections.... Hard to explain. But when in games it will also do this shaky mouse bit even though the game runs fine. If i were to continue to play and provoke this weird thing as it's happening, the computer has and will freeze and blue screen. It's been like this for months, It doesnt always happen but when it does the keyboard and mouse usually attempt to shut off and every time it happens my internet connection will cease aswell, If i troubleshoot the internet problem, Sometimes It does get resolved, but after 10 seconds - 1 minute of use it will go back to ceasing connection and it will not be resolvable without restarting.

So lets rehash:

-Tearing sound comes from speakers and will continue if I continue play
-Cursor moves at slow frame rate
-If continued use of game, result is freezing then blue screen
-Speakers continue to fail during this time, sometimes tearing occurs when provoked, every other time small bubble-esque cracking can be heard.
-Internet shuts off whenever the problem occurs
-Troubleshooting the internet connection leads to resolve which works for 10 seconds - 1 minute before ceasing connection again.
-keyboard and mouse sometimes shut off momentarily.
-restarting of computer solves the issue til it happens again.
-issue is random occurrence but quite common.

Help me /tek/ Ive had asian techies all over it and they dont even know what it is. I've reinstalled Win7 3 times, formated my computer over and over, upgraded the drivers... Nothing is working. However evidence suggests it may be a usb fault.
