Hi,

 

One of the graphics cards on a work computer seems to be malfunctioning (computer freezes and lines all over the screen). So i removed the card and the computer works with the motherboard VGA slot. After examining the card i noticed these 5 blown capacitors so im going to replace them just because i want to see if i can. My question is on the flip side of the board under the non blown capacitors there seems to be like a leak? or maybe its supposed to look like that I'm not sure... do they need to be replaced also? Pic Below Red circles indicate the blown capacitors and the yellow circles indicate the ones that look fine unless you look on the reverse side of the card. I can supply better images if needed.

Thanks! From what i have read im 95% sure its just some glue goo that manufactures slap on the base of some parts to help anchor them to the PCB. I am extremely new to this so i thought i would ask :)

You're welcome.

I would invest in a good solder station to do the work and remember the heat from the solder gun can cause damage to other devices near by, so using a heat sink can be necessary.

Good luck and you're welcome.

Some of today's boards are probably not meant to worked on at the component level because everything is so small and subject to heat damage from the iron, but it's still fun doing it and you never know you might fix it.
