Well, a System Restore, driver rollback and not installing the Equaliser Pack all failed to resolve the issue. I even opened up my case, cleaned it of all dust I could reach, and reseated my RAM (they seemed a little loose) and video card for good measure. That didn't help either.
However, Levi's suggestion to download that EVGA Precision tool and try underclocking the video card did yield some progress!  I underclocked the core clock by 100 points from the stock level (600), to leave it at 500, and just for good measure, pushed the fan speed up to 100 (from 30, which seems to be the auto level). After that, I ran ME2 for a good 15 minutes or so without any crashes or noticeable problems.
I then bumped the fan speed back down to auto (30) because the noise was starting to get on my nerves, but left the core clock at 500. I then ran for another 10 minutes or so before ME2 crashed again. I'm going to try again later by leaving the core clock at stock speed (600), but bumping up the fan speed to 100 and see how I can go without any crashes.
If it works, well... I guess heat IS the issue, but if so, I don't know why the video card isn't automatically speeding up to help cool the card down. (From listening to the fan's higher speeds, it was definitely sitting at a flat 30.) If all that's needed to fix the issue is a higher fan speed, then I'll do some tweaking and figure out a sweet spot between the noise and performance.

My gtx 260 doesn't speed up untill higher 70s(76+) on auto.  I always have mine set at least 40(auto for mine) but bump up to 65-70 its not too loud for graphically intense games gta4 etc..

I would try 65-70 and turn on the OSD (On screen display) Just click the little gears and set it up from there. Moniter GPU Temp , Fan Speed, and add whatever you want.

Underclocking just helping would prove a power issue, but since its crashing with fan turned down only so far,  I  agree and say heat also. 

To sum it up:
I would set around 70 fan and turn on OSD and play and watch temps.  If it gets over 75 degrees or even over 70(I dislike above 70) , you will need to crank it up to 100, remove side door of case, or buy more case fans to get air moving.

Hope that helps some more.

EDIT: If you see the heat stay down low with up'd fan and games don't crash anymore.  Un-Underclock(lol) the card and check to see if stays cool and no crashing.  If it stays low temp and crashs... then you got a power problem or card issue.

Well, another update. Setting the fan speed to 70 results in about a maximum temperature of 68 degrees while ME2 is running at full blast (middle of combat, shooting and powers flying everywhere etc.). Played for almost an hour with no problems whatsoever.  I'm still a little bothered by the noise from the GPU fan, but I'm probably just used to how quiet it used to run. I know my old PC was a lot noisier than this.

Guess it's safe to call 'heat' as the cause of my issues. Odd that I've never had any problems until recently though, as I've been playing ME2 for a couple of months now on the auto-settings and never had much problems. I'm also surprised at how finicky the card is about running at 70 degree temperatures; according to the nVidia website, a GeForce 8800 GT has a maximum temperature of 105 degrees.

Tomorrow I'll try putting the core clock down to far below normal levels (baseline is 600. What do you recommend? 400? 300? Lower?) and keeping the fan at 30 and see what happens. At this stage though, I'm thinking that it is heat that was the cause and not a power or card issue.

EDIT: Oh wait, I just re-read your post, and I realised you were thinking that I was still underclocking my card. Nope. I was running my video card at stock levels (600) during the almost 1 hour of flawless play. I guess we can call my problem solved.  I'm happy; I was thinking I'd have to shell out another couple of hundred dollars for a new video card when the 8800 GT is still beefy enough to run just about any game out there on maximum settings. Anything that prolongs the lifespan of this card is great news!

Hmm if you're comfortable messing around with hardware, perhaps its time to clean the heatsink and fan on the 8800GT from dust? Should be enough just to remove the top cover then blow out all the dust that is trapped inside.

I know it's been half a year, but I know that right now about 100 Bioware employees are still trying to figure out what went wrong and fix it, so let me just give you an update: My card is finally dead (the greenpixelerror became a pinkandgreenpixelstripeerroronboot).

I still don't know why or how this happened and more importantly: Why the green dots appeared only in ME2 at first and nowhere else, but at least I'd be willing to put the blame on a hardware defect now ;-)
