Well, if you were only experiencing a problem with AERO then I would tell you to stop programs running in the background to correct this issue, but seen as you're experiencing issues from your wireless devices and such there's no doubt in my mind that it's a problem with windows, and problem that I can't help solve.The fact that you repaired windows and you're still experiencing the same issue says it all... I would suggest you contact your computer brand ASAP to see if they can correct this issue, and if they can't, they usually HAVE to replace your windows unless you don't have warranty.
I'm sorry I was of no help, but I hope I helped point out the origin of the issue. Please contact your customer support.
