Graphics crashing and eventual PC reset

[UOPayroll_1972]

So every once in a while (rather inconsistently) my PC graphics will go all black or all light green. Some times things will recover and things will resume, other times, my PC just makes noises out of the speakers and eventually shuts off, or I do not wait and hard shutdown. This happens in WoW, a few of my son's games on steam but everything else never runs into the problem.

I have an NVIDIA GTX 560 ti in an Alienware Aurora R3. IS there something out there that can help monitor what is going on so I can look back after rebooting, or can test to make sure if my card is the problem? I can go get a new one to replace it, but if that is not the problem. I am about a year or two from getting a full new rig, but in the meantime, have to keep this puppy going.

Is your sound through HDMI?

No. I got an HDMI connecting monitor for Christmas but this was also happening before with the DVI connection
