Ok, we will figure this out. :) Post what you find.
Well that was odd - for the first time in days I was able to play Left 4 Dead 2 without any crashes - played for well over an hour, had the GPU-Z log my GPU information (attached file, periods where it rises into 70 C and above is when I began gaming, approximately 1-2am). Maybe GPU-Z helped somehow? Not sure. I'm heading to bed soon and will leave my computer off while I sleep, I'll try the benchmark game again tomorrow, if it still runs fine I'll try something more strenuous - for now, not exactly sure what changed to make it work this time, all I did was install GPU-Z.
Could be as simple as a dust bunny lodged in/under the heat sink or the fan not spinning constantly. For the time being I would try to borrow a working card and see if the computer still crashes. Or leave the side panel of and point a room fan at it (not as a permanent solution of course.)

So I have been testing over the past couple days with mixed success - I was able to engage in several long (1-2 hour) session on my benchmark Left 4 Dead 2 without any BSODs - however, in the past 24 hours, I was trying a less trenuous older game, Titan Quest, and experienced the BSODs anywhere from 5 to 30 minutes into playing. I've been recording with GPU-Z and the last crash is visible at the end of the last log - the GPU is at about 90 C then I get the BSOD. I have all the latest nvidia drivers for my specific card, so that isn't the issue. I have the cover on the side of the pc ajar and a small fan blowing towards the inside of the pc, anything else I can do to stop the overheating while gaming? I felt the card after one of the BSODs and it felt quite warm while the rest of the interior seemed a normal temperature.
Well 90 C is definitely too high (almost at the point of boiling water)
So it seems to be the card itself that overheats for some reason and ultimately crash the computer as a means of self preservation. If the card fan/heat sink is clean, you might either have to exchange the card or mount a better cooling system (if that is possible on your model). Next thing I would do is removing the heat sink clean the heat sink and gpu, and apply fresh thermal compound (not more than the size of a pea!).

How do I clean out the card/detach the heat sink? I will check to see if there's a manufacturer warranty on the card, not sure if there still is though.
That's a little different for each and every model but you'll get the general idea when you watch this tut. Arctic Silver is a good compound. (Pay especially attention to how little compound is needed ! It's not about gluing the parts together but to close microscopic gaps in the surface material to reach as much connection as possible.)
