Restoring flexed graphics cards?

I can't seem to find much information about this, other than information from the xbox 360's motherboard flew issues. Thought it would be better in the form of discussion. I bought a computer in a shady street deal some months back, had some issues (my fault for not checking it over better). It had two of these.

I get severe artifacts as well as screen flickering, unsolvable with software tweaks such as OC ect.. I decided to just keep the less damaged of the cards, sold it to a friend, only to have it eventually fail some time down the road..

This dude was hardcore nerdin it up /w some stuff I don't even wanna know, but what was really stupid is that he wedged a fan in between the two cards, adding tension, who knows how many heat cycles making board flex over time. (I guess the chip-set was getting hot?. Moron.)

Back to my main point, anyone have any experience or methods in restoring boards like this? I'm doubting it to be a component issue, more likely caused by flexing, maybe take a heat gun to it really good? Chemical methods?

thankz

 

bump.

 

If even one of the circuit pathways is broken, then the card is a write off.

Flexing a card the amount you have described would indicate that this is probably the case.

 

An its probably not easy to fix huh, iv tried heating it up really hot with a heat gun ill see if that does anything.

 

Well, let us know whether that's worked. I'd say the chances of success are very slim to none.

 

Heat gunning it is likely to melt the protective coating and possibly some of the circuit pathways, not to mention the solder holding some of the components onto the board.
