Ppro openGL crash/TDR

Question

I have a thread about this open at the nvidia forums as well (http://forums.nvidia.com/index.php?showtopic=217020&st=0&gopid=1336480&#entry1336480) but the more eyes on it the better I suppose.
PC specs:
asus p7p55 lx motherboard - BIOS up to date
Intel i7 860 - default clock speeds
16gb RAM - unsure of band
Zotac gtx580 - standard edition with default clock speeds
3 1-1.5tb sata6 HDDs setup in typical fashion for editing
750w thermaltake PSU
Win7 64bit professional - up to date
Nvidia driver version 285.62
Page file set to 24Gb
Basically here is the situation.  We bought a gtx580, 16gb kit and a 3rd HDD for my system at work...installed them and had no problem.  My copy of cs5.5 came a few days later so we installed that.  Ran into power troubles because my system had a 550w PSU...so we disabled the 3rd HDD to get css5.5 installed.  I did some test encodes to compare cs4 to cs5.5 with MPE speeds and it was great, a lot faster.  The 750w PSU got installed a few days later along with the 3rd HDD and the troubles began.  Anytime I work in premiere with MPE enabled I get the win7 TDR (display driver crashes and recovers...forcing a restart of ppro/ame).  This occurs most frequently when encoding in AME but will happen quickly if I edit in Ppro using MPE hardware acceleraration.  It even happens when I have mpe in software only mode while editing...although this occurs significantly less often.
Things I have tried to fix the problem...
-Rolled back drivers to 275.xx....clean install of 275.xx, 285.xx and the 290.xx beta drivers. All of them produce the same issue.
-Disabled the audio device with the same hardware ID as my video card.
-Over and underclocked the card's speed.
-Updated motherboard BIOS
Things I still need/want to try:
-Swap back to the 550w PSU to exclude the new one as faulty.
-Swap the gtx580 into another workstation to see if it produces the issue.
-Run burn in tests like prime95 and furmark to rule out the RAM and see if furmark crashes with the openGL stressing.
We have a gtx570 in the mail and it should be here soon.  I believe we will be putting it in my pc and the 580 into another to see if the 580 crashes on other systems or not.  I also have read about plenty of TDR issues with firefox and games with the recent nvidia driver releases so it could simply be a driver issue and unfixable until a new driver comes out to address the problem.  I'd prefer to troubleshoot all aspects of hardware to determmine if it is faulty hardware or not but it is my work machine, so I don't have permission to do whatever I want to it.
I have noticed that if I work with our camera's native avchd codec...the crashes occur more often than editing with a converted (mpeg2 bluray m2t).  It doesn't say much other than the crashing happens more oftennwhen the GPU is actually working.
My current 'solution' is to disable MPE so I get less crashes but it is still frustrating to work with.  If anyone has similar experiences or suggestions, they'd be much appreciated.  If I'm missing any info or details, let me know.

thats a weird thing going on with the openGL.  I've had some experience way back in past with gaming and 3d gaming with glide and open glide and various other 3d gaming stuff ( direct x etc is included in that mess ).
as things progressed with hardware and software everything in gaming changed ( re: openGL etc ). A good example is probably FSX and so on.
It's always been my impression that openGL was for gaming only and should just be shut OFF when on an editing computer.  If not shut off then disabled or whatever... as it just doesnt have anything to do with editing or maya or AE or stuff like that... and might confuse the computer re: what features of the graphics card it is supposed to use.
I am not a technocrat or engineer but maybe by taking card out ( rebooting, reinstalling etc etc ) you are just clearing up the OpenGL for "gaming" drivers that somehow conflict with the use of the GPU to do your editing work.
If you disable the openGl and just edit.. and dont do " gaming" that might solve your problems IMO.
