While trying to upgrade the cooling on my Grandmars or Chaintech GeForce4 TI 4200 128M A-GT21 I broke off a little brown capacitor or transistor, im not sure which. It is on the back of the card in a little white box labeled C105. I would like to buy a replacement piece and solder it back on. Do you know the specs of this little component? Where do I get one? Please help! Thank you. Robert.
