Strange Video Hang Up

[andtheedgoesmoo]

I've been having this strange video hang while watching videos online or sometimes my games will hang too. The video or game will suddenly stop, then make a loud "BRRRRRRR" noise, and then resume playing. I first thought it was my video card so I tried a new one, but the issue was still there. Then I RMAed my ram and motherboard because i thought they were the issue, but no when i put it my replacements, the issue was still there. Then I replaced my PSU to a hx1000w but the issue is still there! I'm starting to think its either my hard drive, or a software issue. Anyone have any ideas?

Mine does that as well and I have none of the same hardware as you. It seems to be associated with my wireless internet connection. I will often loose my connection when this happens and have to let windows shut down my card and reconnect.
