GT 1030 Gigabyte 2GB GDDR5

Seller Note “This card was tested in my PC and showed no power the fan didn’t spin  and showed no display parts only”

Issues:

  • Upon visual inspection (naked eye) the card appears in reasonable condition. However, a digital microscope reveals multiple instances of PCB damage (dislodged minor components, scratches revealing PCB tracks) – this card has been badly treated, the seller might not have realised this, so I didn’t give negative feedback.
  • Initial multimeter measurements suggest at least one short.
  • Assuming damaged components can be re-soldered, it’s hard to know the full extent of the damage at this stage.
  • This could be a hard repair for my current skill level.
