Crakling sound with Intermintent Freezing

Hello fellow geeks, I am having a nasty problem that hinders my game play with some games and not with others. Every once and awhile I will be playing a game like CoD:MW 2 or WoW Ill get a blue screen that will restart my computer to stop a fatal system error. When I get the games running again the sound will crackle, like if your headphones got blown or something, and freezes every minute or so for a few seconds. It gets worst when I get into fire fights in CoD: MW 2 and in WoW when I am in a high population area. after a few days the problem will go away and i can play my games fine but its unpredictable on when its going to start. this problem could be happening in CoD and WoW but I could play games like L4D2 and Dawn of War 2 without any problem. I have had this problem for almost 6 months and have reformatted multiple times and replaced my hard-drive, because of a corrupted hard-drive, not to fix this problem. It kept happening after that though.

I have linked my DxDiag file so refer to that to see my computers specs

Also to note it happens when I defrag my computer but not as bad when I get the blue screen.

Thank you for taking the time to read this and I look forward to your response.

 

I recommend looking at the minimum requirements for those games and making sure that your computer goes above and beyond those numbers. Or just put the games on lower settings.
