How to fix broken Nvidia or AMD graphics card with hot air station.

Ok, I must to say , that this way of repair couldn't grant you a 100% result. But sometimes it could help. The main purpose , is to heat soldering under the chip. As you know , BGA can 'disengage' and there is a low contact with a board (PCB). So , there is a tip how to fix it. BTW , if you don't have hot air station , you can try another ways of heating , but remember , to heat some chip ,the temperature of the fan must be about ~220-240 ºC (430-460ºF).Also , you need to heat it about 5-8 minutes , to get the result.

Like the submerged batteries, if you warm up beyond room temperature, you gain some minute functionality :)

Interesting video, i learn something every day, thanks for the tip.
 

A nice trick I found was to run water over my graphics card for a couple minutes then quickly throw it in the deep freeze, after a day or two I would put it in the oven at 160 Celcius for 20 minutes. After that you (using oven mitts because safety first) run and put in the the pcie slot and quickly boot your pc.
