Deective 6850?

[creature]

I just built a computer and installed windows XP pro - 32 bit. All OS, MB and GPU drivers are up to date. If it makes any difference, I am playing on my 42" 1080p LCD TV.

Link to my build:http://www.tomshardware.com/forum/forum2.php?config=tomshardwareus.inc&cat=31&post=349058&page=1&p=1&sondage=0&owntopic=1&trash=0&trash_post=0&print=0&numreponse=0&quote_only=0&new=0&nojs=0

So moving forward, I installed Diablo III. When I start the program, I get a grey screen and it stutters to get to the login screen. One time I tried and it just bogged down and didn't want to run. Then I tried again and it stuttered through but worked. The third time I got a blue screen and the comp restarted, the fourth time it stuttered through but worked. When I am able to get past the login screen, the game runs great.

Also, I've noticed that when I boot XP, after the XP logo comes up with the status bar below it, but before it shows me the login screen, it flashes a pinkish/purple screen.

UPDATE:
-Of the ~15 times I've logged into windows, only one of the times after I clicked my login profile, the video card did its 'not responding' thing.
-About 10 of the 12 times after I've opened Diablo it has happened.

After speaking to some people, it was brought up that it might be my RAM causing the issue. So I shut down the comp, took the RAM out, did a quick visual, everything looked OK. I put one stick in tried again, same issues. Changed out the stick, tried again, same issue. So either both sticks are bad or they are both ok.

How do I test to see if my graphics card is bad. I have an OLD Radeon 9000 PRO 128 MB from like 2003, but I dont think that will do me any favors. I can take the 6850 out all together and see if I still get the pink screen but it wont run diablo without a gpu. I'll see if a friend has a card I can try but I doubt it.

Suggestions?

make sure you have the cpu code and ram updates installed on your mb. new x68 and z77 need cpu code updates for ib cpu.
in the bios make sure the pci gpu is the first video device and make sure you turn off the onboard video and mvp chipset to run both onboard and dedicated gpu at the same time. the mvp and luicent software that "sold as to speed up gaming" works on a few games but has more bugs in it then it worth.) on my z77 sabertooth i have that chipset turned off.
when you install windows xp and rebooted did you go to intel driver download and download the intel chipset update and the updated ssd driver software. then rebooted and went to amd/nvidia web page and downloaded the newest drivers for the video card. then rebooted and let windows install all the service packs?? one of the thing xp needs to have install and play games is directx. it not installed by default. (windows 7 has some of it installed.).

When I installed, I had already downloaded ALL of the drivers onto a USB card (for MB and GPU) I installed all of them and then restarted. I then installed all the XP updates, I even did the optional updates. I also have the latest direct x.

I'll double check the CPU code and RAM updates but I think I've already done them. I think I have sb, not ib cpu anyways.

I think the BIOS is all set but will double check the BIOS settings. Thanks for the input. I will update tonight.

If this all checks out, is it RMA time?

The bios settings were ok, but i diabled integrated graphics just in case. Still getting the issue... now what?
