Computer freezes and makes buzzing noise, no BSOD?

[Dominicoben]

So a few weeks ago I was in Sony Vegas editing a video and suddenly my mouse and keyboard both became unresponsive and a loud buzzing noise started coming out of my speakers. I left it for a few minutes but nothing happened, there was no blue screen of death, no error message,nothing. so the only thing I could do was force a restart.

Over the next few days the problem continued in graphical/CPU intensive programs (such as photoshop, Vegas, fsx, etc), and all I could do was restart. Not once did I see an error message. I did originally think that it was due to an overclocking (4.4 GHz) however I checked my temperatures and they didn't ever peak above 60-70. Neverthelss, I underclocked back to 3.3 but still experienced the problem.

I read online that I should do a clean install of windows so I did that, and up until now I thought the problem was solved. And a couple of minutes ago I was playing age of empires and the computer froze and then The buzzing started again.

Here's video I recorded of the sound: youtube.com/watch?v=JiyAqeuGreU

I'm really clueless to what it could be. Ive reinstalled NVIDIA drivers, cleaned out the registry, reinstalled windows, what can it be?!

I think it might have something to do with my graphics card or drivers or something along those lines, as the problem only occurs when in games or video/picture editing programs. However, my computer and all the components are new (about a month), and I can't think of any possible meddling I couldve done to cause these issues. After all when I first built the pc, I was having no issues whatsoever.

Here are my specs:

Intel core i5 2500K
Gigabyte P67X-UD3-B3
8GB RAM
NVIDIA GeForce GTX 560Ti
Seatgate 1TB Hard Drive, 7200rpm

Any help would be greatly appreciated. I'm running out of ideas!!

I would say its a graphics card problem, I have had the same happen to me before but that was due to me putting a heavy overclock on my card. I have also had the same happen with a couple of old graphics cards that died.

Although the computer is new, it is know for graphics to fail at any time, if you have the chance you can prove it by testing your pc with a different graphics card, if you don't have access to one then I would either take the pc back to where you bought it and get them to test it, or if you built it yourself I would RMA the card.

Ideally it would be good for you to try another card in your PC first to make 100% sure it is the card, but it certainly sounds like it to me.

I'll try another card, but I would have to put it under frequent use to be able to tell if that was the culprit. The freezing is so irregular that I have no idea of when it will happen next!!
