These are my (important) specs, just posting this here to save time.

Recently when trying to run a game like Civ V or Sonic All-Stars Racing Transformed at max settings at 1080p, a strange buzzing noise is emitted out of my speakers and the fans of my graphics card whir quicker than I've seen them whir, leaving me with the sole option of turning my computer off (it is completely unresponsive). There is no error message, no blue screen, just my computer going in a state where it cannot do anything, forcing a hard reset. Sometimes the same problem happens and it restarts. I have been using this build for 3 months and I have been able to run all sorts of games like Crysis 2 with no problem. This problem has only been happening recently.

I have checked my temps with HWMonitor, while idle and while in a game and they are fine as far as I can tell. 20-40 degrees with my GPU, and 30-55 degrees with my CPU.

I have also reverted to previous drivers, dusted my GPU and reinstalled my OS. None of these worked. I'm currently thinking of RMAing the GPU, should I?

Thanks in advance.
 
run Memtest always for errors like this: www.memtest.org

- create a bootable DVD or USB stick
- boot to it (change boot order if need be; disable USB quick boot if using USB stick)
- run at least ONE FULL PASS or until an error

If it's a different problem, my first guess would be a graphics card problem.

Just ran it, got one pass. I'm going to leave my computer on for several hours tomorrow to see if it passes multiple times. I doubt that it is the RAM though.
