^^I have tried reflowing in an oven but I mostly reflow using a heat gun on the core only now. I don't know that there is much difference in outcomes to be honest, but it seems safer to me to just use a heatgun on the core. Thinking about trying an oven on a 5970 I have that will not post though.

Its not too bad. I use a mini handheld torch with a "heat" attachment to flow the solder on the pcb. Wipe that off.... Then use a little solder paste you can buy online(it has silver, flux, and some other crap and basically comes out of a tube like goo). place the replacement smd caps on the paste... Use the torch to flow the solder paste...
All that said, I've found that replacing caps is pretty iffy. If the caps burnt out there was usually another reason that they did...
If you just knocked the caps off then replacing them has a better chance of working.
Let me know if you need any other advice.

The capacitors and everthing else are fine. Thx for the tips.
Ahh.. grade 9 tech class... its all coming back to me ! ;p
pEACe
Even tried sticking a card in the oven?
Depends... Most cards that I have messed with that have that problem are not repairable with a reflow but sometimes its worth a try. Usually what happens is I'll reflow them, they'll start posting but will still artifact... Still aren't worth gaming on so I usually just leave them alone mining untill I need them for video output...
When this happens the cards probably need to be reballed... I however don't have the setup, and wouldn't feel comfortable doing that.

What do you think about cards that function as secondary but won't post as a main card.?

itty bump. 
Is transplanting a pair of pcie smt resistors as easy as it seems ?
I'm tempted to buy a cheap gun so I can replace the missing gtx 460se resistors with the ones off a dud HD 4850.

What would you pay for 6990 with an artic cool fan setup? Also if only one of the chips are acting up is there any way to fix it that you know of?
Maybe a problem with the vrms... or some part of the power circuit feeding into the dvi. Try undervolting and lowering memory and core clocks and see if it stays stable for longer.
Unfortunately I have so many cards on my hands right now I'm mostly looking for the high mh/s cards. PM me if you'd like help trouble shooting though!

^ I have a 5830 sitting around that does something similar... But it'll mine for a few then reboot... I have a feeling it's something to do with the DVI port.. If it's plugged in it dies right away.. If it's used as a secondary card it seems fine for a few.... then dies 
I have a Powercolor 6770 that semi-works. Tends to cause machine to reboot itself after about 30 seconds of use. I'll get rid of it for 2.5BTC+shipping, have box. PM if interested, normally over 200mh/s out of this card.
^Replied.
Did further testing, here's what I have:
5970 that boots and displays graphical output for a while, but when launching something graphics-intensive the driver continually crashes until the screen stops showing anything.

Just curious, what price (in USD or BTC) would you pay for my 5970 which boots up an displays output, but seems to have issues with instability? Doing further testing right now.
I have a 7950 that the fan turns on but I cant get the rest of the card to work if your interested
I have a few 5830's for sale.......
^Thanks I will try that.
Also: Last bitcoin I owed JJ is sent.

I'll bet you won't need the mv bump if you try using cgminer to limit gpu usage to 97-98%. Or try bumping up the memory.
I undervolt my cards substantially... even have the memory undervolted on the 7970... and If I'm mining and watching video the drivers sometimes freeze. Granted I havn't played around with the settings much in cgminer but its not much trouble to pause the miner and play whatever I want... Then start it back up again.
I may try adding back 10 mVolts or so and see if that helps.
