I got a new Nvidia 9800 GTX, and installed it. When the PC boots up it shows the 9800 gtx, then when Vista boots it no longer recognizes it. I disabled the onboard video but no luck yet?
Yes, it all loads normally. Except for the fact that it does not see the video card. It's bizzare bacause it is plugged into the GFX card. Card fan is running, and the onboard is disabled, but I still have my desktop. Even checked bios and the primary is PIC EX, not onboard.
I added a new 550 W psu, and it's got 3 MBPS of ram. It's an emachine that I want to give to my son to play games. It's running 32bit vista. PCI ex is not 2.0 I dont think but I thought PCI ex 2.0 was backwards compatible?
When you say it shows it. Where is it showing it ? Have you looked in the device manager ? If not take a look, if its got a yellow question mark or triangle under display adapter then most probably the driver you are using isnt recognised.
