Whether on Windows or Ubuntu, Chrome or IE within a random amount of time, my computer freezes and needs a hard reset. Usually there's a loud buzzing with it. I've tried replacing the video card and my sound driver is up to date. This happens about 95% of the time while streaming videos such as on Hulu. I can spend all day playing Skyrim or WoW without a problem and after just a few minutes on HUlu every time, it will freeze. Any ideas?

A memory problem is the first thing that comes to mind although I'm not sure about the buzzing. How much memory is in the PC? How do you know when a politician is lying? His mouth is moving.
I assume that means 8GB ram in 4 2GB sticks. That should be plenty to stream video. It has to be a hardware problem if it's happening on 3 different operating systems. I'm assuming that all those operating systems are on the same PC. Is that correct? How do you know when a politician is lying? His mouth is moving.
Yeah that's 4 2g sticks. On both Windows and Ubuntu OS. And yes on the same PC. I thought it might be the graphics card, but it happened with 3 different cards. I also thought it might be an audio issue, but my driver is up to date. I've completely taken apart and put everything back together multiple times to ensure good connections. The thing is, I don't understand why it's only while streaming video- even on the default youtube setting, while I can run something like Skyrim with relatively high settings.
What about the power supply? It may not be providing enough power to the motherboard. That would account for it happening on both OSes. Or maybe the problem is before the PC. If you have a cable provider, check for lose coaxial cable connections. Is there a separate router? How many machines are on the network. Disconnect the other machines temporarily.

My PSU is a modular 700w thermaltake. I think that's way more than I even need. There's me and another computer connected to the network switch via e-net cable. The other computer has no problems. If it was a bad connection, wouldn't I have a problem with online games as well?
why not do a mem test to see if the ram is faulty?

I finished 7 passes with no errors today on memtest86+, so it looks like that's ok.
