Random freezes, screen turns a solid color

Hello. I have an issue that started about a 3 and a half weeks ago, and I have so far not been able to fix it or figure out what is causing it..

I sort of have a dual monitor set-up; I have an Acer monitor as well as a Cintiq that is always on. The issue I am having is that my computer will randomly freeze up and each screen will turn a solid color, such as white, brown, gray, black, purple, pink, etc (if it matters, neither screen is the same color when this happens) - now, my computer doesn't actually freeze - everything is perfectly fine until the screens blank out. There is no sluggish mouse movement, lag, or anything like that. The reset button on the computer works instantly to restart it and it boots up fine with no errors.

I have so far:
Done windows updates
Updated graphics card drivers
Updated anti-virus
Scanned for malware
Monitored temps, they all seem fine
Cleaned out computer (dust)
Reset graphics card
Made sure all fans are running
I've checked the event log, and all that is there around the time of the crashes is event ID 41, which appears to just be a generic unexpected shutdown. There are things under the error logs, but nothing that jumps out

When I first updated the graphics card drivers, I thought I had fixed the problem, I went over a week without it doing it again - now, tonight, it's done it 3 times. Each time it has happened, as far as I can recall, I have had world of warcraft open.

My computers specs are:
case: rosewill ranger-m dual fans mini tower
Windows 7 64-bit
Intel i5-2400
Nvidia geforce gtx 550 Ti
ASRock H77 Pro4-M
16GB DDR3 ram (g.skill ripjaws series)
Corsair 700-watt power supply
Western Digital HD (WD1002FAEX)

also:
razor naga epic
razor anansi
western digital my book external HD
sennheiser wireless headphones

As far as temperatures go, my graphics card is about 60C when idle and reaches about 73C when I have Warcraft open. From what I read, these are normal temps for my card.

My processor is around 40c.

I have monitored these extensively and the few times I've looked right before a crash, they were all low/normal, so I do not think it is a heating issue. This DID seem to start very shortly after a forced windows update.

So... it it my graphics card? Is it just a software issue? I'm getting really frustrated over here!

Could be the GDDR overheating. try manually setting your fan speed to 100% in afterburner and see if this reduces the occurrence of this. The lower spec GPU's use shittier GDDR modules and usually poorer heat solutions (especially for the GDDR).

I have some new information, I looked in my "important messages" for Windows and I saw this:
"Problem: Video Hardware Error"
it seemed to point to a dump file, and couldn't resolve the issue, but once I clicked out of the window that message disappeared and I can't figure out how to look at it again to see the file names it pointed to.

I also ran a memtest for over 8 hours and had 0 errors.

memtest does not test your GDDR. Only the system RAM.

I think it is almost certainly the GDDR. Did you try running the Graphics fan at 100%
