My ACER Aspire 5920G is provided with the Nvidea GeForce 8600M GT Graphics card. I have high evidence that this is defective so I have te replace it.
I opened the bottom of the laptop (after having removed the battery) and I think to have identified the card: the metal part under the yellow-copper shaft that extends alongside the processor fan. The WiFi "Antenna" is situated above this cage. This card is attached with 4 screws. After removing those the metal cage can not be taken out so I shall have to do more than I did up to now.
