Right, I have a potentially serious issue:
My new computer makes a strange, high frequency buzzing noise. It happens during games, but also occurs when I'm scrolling(?) and moving around webpages.
Now it sounds a lot like it's coming from my PSU. I did some quick CPU/GPU tests and temps seem normal, plus there's no strange behavior nor lag in games. The noise is also coming from the back/bottom of my case.
This would be a minor inconvenience if my computer didn't crash to a grey screen after an hour or so of gaming. Everything inside the case stops, the screen turns to grey and my PC hangs until I force a shut down.
Any ideas what this issue could be? If it is the PSU, what might be the problem? Or is it perhaps an unrelated driver issue, and there's just some coincidental loose screws? Windows and AMD are all up to date, so I'm starting to think it's a hardware issue...
Critically, can anyone suggest some comprehensive stress testing software I can use to eliminate certain components from the suspect list?

*EDIT 2* - Might be worth mentioning that despite the constant noise, the crash has only happened in Battlefield 4 so far. I've had two hour long games of DOTA and everything's been fine.
Can someone suggest a good reliable stress test I can run just in case it IS ONLY BF4 causing issues?
