How to fix a broken nVidia 7900
graphics card
I am going to talk about how to fix an old nVidia 7900
graphics card from an old Dell Inspiron 9400. When you try to start your
computer and the only thing that it does is showing you a blue screen, it is
time to try this procedure.
First of all remove the computer´s covers so that you
can get to the graphic card. Remove the graphic card and then remove the
graphic card´s covers. You have also to remove all the plastic parts of the
card. Once you have the card free of other parts you have to prepare your oven
to put it into.
Cover the oven´s tray with foil and make four balls of
foil in order to place the card over them. Put the try into the oven and set
temperature and time. Temperature must not be above 200º C and the time should
not be less than 20 minutes.
After this time wait until the card cools off before
placing it into the laptop again. Once it is cold fit it into the laptop and
make it run. If the computer works again Congratulations! if not, repeat this
procedure again.
This procedure must sound crazy but it is true because
I did it myself in the computer I am writing with now. It has a strong physical
explanation and that is the fact that a metal melts with the high temperatures.
As you know, in an electrical circuit there are
soldered joints between electronic parts and these joints often brake up due to
overheating and so the circuits stop running.
But, why do you have to set the oven´s temperature at
200ºC? The joints that I have mentioned are made of Tin (Sn). Depending on the
Tin alloy, the fusion point could vary between 180º C to 230º C. by bringing
our card to this temperate we rebuild these joints, so we make the circuits
work again. Simple, cheap and fun, it is not magic, it is science!!!
