New monitor, screen turning black, freezing, artifacts? (GTX 680)

Hi, my birthday was a few days ago and I received 3 BenQ XL 2420T 24" monitors. The purpose was to play games with Nvidia surround and 3D Vision using my GTX 680 (4GB)

I first started with just 1 monitor, as I had no desk ready to fit all 3. I removed my old monitors and plugged in the new one using a DVI cable, then setup the 3D Visions 2 glasses and software, installed drivers, etc. This all ran fine for a day, but ever since thursday I've been having issues.

Randomly, while playing games, browsing the internet, or anything really, the screen will go black and whatever audio was playing with sound distorted and it takes about 10 seconds for the screen to return to normal. Sometimes there will be artifacts all over the screen before and after the event, but other times there's nothing. This happens around every hour, and the GPU is not overheating, I'm in an air conditioned room and the GPU sits at below 40 Celsius usually.

Besides the monitors and 3D vision, there have been no hardware changes and I have tried uninstalling and reinstalling Nvidia drivers, which fixed nothing.

Thank you for your time.

    Did you try any of the other connectors like the HDMI or Display Port. Or the other DVI?

    I'll try that now, but as far as I know there's no way to replicate the issue so I'll see if it happens again.
  2. Just happened again, this time in a different DVI slot.

    For the first time though, I got a display driver has failed warning afterwards

    It could be a coincidence that it started happening when you got the new monitor. This is either a corrupt driver or bad system RAM. I had the same error with my PC that has an Nvidia SLI setup. I thought it was the GPU driver at first because it only happened during games. I did a memtest86 RAM test. Turns out one stick of my RAM was bad. Do the memtest86 test first to make sure. Make sure it runs several passes. Nothing might show up in the first pass.

    I ran a memtest86 test and it made 5 passes with 0 errors. Still having issues.
  4. I don't think it's the VRAM because the problem still happened with only 1 of the new monitors connected and no 3D Vision. I've turned down the clock speed and so far it's fine, but it hasn't been very long.

    I have a 750W PSU -
