Well, you won't actually see it - as long as I don't have anything which could be taken as real camera. But let's start from beginning.
There was a great hype last year with baking video cards (yeah, I mean in oven). Basicly somebody tried to bake an old VGA to see whether there are just some broken soldering points either under/in GPU or somewhere else. Guess what, it worked than so this spread all over the world. Now some people are still triying this even if the problem is usually somewhere else (like for Radeon HDs 4xx0 - usually VRM or something dies here). But hey, you could try, it won't do any more harm.
The problem is, there is hard solder used on all newer cards so it often dies again after time because the solder didn't melt at all, it just softened. That's the reason I'll try my HD 3870 to be just heated in oven an than I'll continue with hot air pistol (550 °C) - I am certain it could be because of broken solder points (after my Accelero lost pressure when my PC fell from bed), I was increasing it for so long that it won't boot at the end).
Also most of the people bake the card with capacitors on - and this is one of them. So the great deal is visibly leaked Nichicon (this guy said that won't matter) and X-CON ULR's. Result is a few of them are visibly bloated, capacitance is 30-40 % lower. As for ESR, well, I used meter with scale as folows:
0,1
0,3
1
3
10
etc.
It showed me 3 for all caps so I gues all of them are considered as bad now (e.g. ULR 470 uF/16 V has ESR as low as 0,011 Ω in datasheet).
Anyay, they did not die under service, just did not handle 200 °C first and than quarter of hour at 250 °C.
