I am trying to upgrade the video card on Model T2460 Emachines to a XFX Geforce 7800GS AGP 256mb DDR3 DVI/VGA/tv_out card. My computer has the following: 2400 AMD Athlon XP Home Edition Processor 256 MD DDR 3D ProSavage8 w/ available AGP slot (this is the vid card) 60 GB Hard Drive Model T2460 Emachines I am having issues installing. When I started I disabled the video card, and shut down the CPU. When I booted back up, I had no graphics after replacing old card with new card. I switched back to the old card, and still no graphics. I had to keyboard control my way through and went into properties to enable the card, still nothing. I unplugged the card. I popped the system battery out for a little bit for the motherboard to reset and system came back to normal I think. Can anyone help me replace the card? Thanks in advance!
