GPU/Monitor - Random Screens of "death"

I recently built a new computer a couple weeks ago, and I've been having a problem with random screens of "death". I haven't been able to figure out what's causing them, so I'm hoping there's someone on here that could be of help

Here are 2 pictures of the problem (sorry for the large images):



I've only had it happen when I'm playing World of Warcraft (though I haven't run any other graphically trying things), but the times that it occurs have been random. I've had it after 30 minutes of playing, I've had it after 4 hours of playing, and I've gone for a couple of days without it occurring...

My whole computer doesn't freeze, just the screen goes bonkers (i.e. if I have music playing in the background it will continue play once the screen cuts out). The only odd thing is that if I jiggle the wire for my monitor, THEN my music will stall.

As far as I can tell, it's not an overheating problem - I've tried all the normal overheating solutions and none have worked. Also, I ran GPU-Z until I got the error to check for oddities, but I can't spot any. I uploaded the log to Megaupload (since the 521kb size was too big for the forums) too if it'll be of any use: http://www.megaupload.com/?d=NHRK4M6K

My computer specs are in my profile, but here's a link to a Newegg wish list with all of my components: http://secure.newegg.com/WishList/Pu...Number=8568829
(NOTE: I'm using an Acer 19" monitor, shown here http://www.newegg.com/Product/Produc...-073-_-Product I just couldn't add it to my wish list because it was unavailable =P )

I appreciate any help and feedback that I get! Thanks in advance!
Also, if I left out any info that could be useful, please let me know

That's strange. Are you using the latest ATI driver for your HD 5770 card?

Does the Acer monitor use a driver also, if so, do you have it loaded?

BTW, nice system you have there! I am a little covetous.

Thanks Nib =)

I do have the newest ATI driver for my graphics card (installed it twice to see if maybe the first install didn't complete or something), and I got the latest update for my acer monitor about a week ago.

I'm wondering if my monitor is just going for some reason... I'm gonna have to see if I can scrounge up an old one and see if it still happens. Otherwise it seems like I'm looking at a Graphics Card or MoBo problem

Did you install the chipset drivers for P55?

Here's the latest from Intel on the P55 chipset driver:
INF Update Utility - Primarily for Intel® 5, 4, 3, 900 Series Chipsets

Thanks for the info you two! I think I installed the latest chipset, but I can't remember off the top of my head, so that's probably a sign that I forgot it =P
I'm currently in the process of heading back to college and all that fun stuff, but I'm gonna have to see if that was indeed the problem when I get my rig set up again!

So after getting everything updated and all that good stuff, I'm still having those random screens. I updated to the new Catalyst CC 10.1 as well, but it's still happening... Bleh.
