typically it gets overheated and you can tell if this is the case by the green board turning brown. (especially around the regulator heatsink and the backside of the main GPU die) they are getting to be a rare as unicorn poo.
if you know at all if it worked...maybe... but chances are really REALLY slim. you really got to get these cards before they grenade.
that said, i may have one in my parts box. i'll have a fish around and see.

The backside looks normal. I'll change all of the caps and hope for the best. This card was dead when I got the GT2005 board.
MrMatt:
What I'll do is replace those polymer caps and measure the two voltage regs, if either of those aren't working properly I'll replace them and if it still doesn't work I'll toss the GFX card.

usually the biggest culprit of these kind of random boot issues is the 4 small caps under the heatsink ive circled together. but generally i replace al the circled ones.
but i think if you take out some of those 4 caps, youll find them blown out on the bottom where you cant see them.

I've just finished replacing all of the caps you circled and the motherboard still has the same issue, all fans spin up, there's a green LED on the board but it doesn't boot. The HDD spins up with power but there's no activity after that.
Am I missing something obvious in the connections?? I've put this system together dozens of times but it feels like I'm missing something.
Just to sum up, the PC wouldn't boot one time, then worked when I pulled the power cable and replaced and played fine all day. Then the next day it wouldn't boot up again. I saw a blown cap on the motherboard and 5 on the GFX card so I replaced all of them and the PC booted fine again. It worked for a few days until I tried to put it all back together again in the cab. I also tried to upgrade the RAM from 128MB to 512MB at the time this happened.
I've now tried a raplcement GFX card but the fault remains when using that card. I got a replacement CPU but some of the pins were bent and missing (damn you eBay!!).
MrMatt:
If I start the PC without the 4pin 12V power connecter then the PC does the same thing as with it connected. Could this 12V be missing on the board? There is 12V on both pins on the MOLEX.

it's generally a good idea to swap out most of them if you find blown out ones. (basically anything bigger than 100uf but there are exceptions)
if you post a nice clear pic of the motherboard, i can use my awesome mspaint skillz to tell you all the ones that are going to need to be swapped out.

I've still got a few new caps leftover. Is it worth changing some more to see if it fixes the motherboard, and if so which ones should I start with?
