9800 gtx problem with mobo

[jackyle]

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?

Please help.


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.

My Mobo is http://www.e4allupgraders.info/dir1/...P61PM-GM.shtml

MCP61PM-GM

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?

I appreciate the help.

Have you tried an older driver version? It seems like a driver issue with Vista.

PCI-E 2.0 is backwards compatible, so that isnt the problem.

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.

This might give you some clues. Others here report issues wioth older chipsets not compatible with newer cards.

Are you sure that all of the extra power connectors are properly attached to the card?

He said the fan was spinning on the card. That means that there IS power going to the card.

When are you getting a black screen? When you start up, or when you go into windows?
If it is when you start up, it is most likely because you disabled the on-board video.

It's when I go to Windows. Thanks for the help.

Boudy, your right I desabled the onboard video, now I seem to be screwed. All I get is the black screen. Man I messed this up.

 

[jackyle]

Ok I cleared CMOS so now I get use my onboard video.


Here's what I now know

I have NVIDIA GeForce 6150 GPU and NVIDIA nForce 430 MCP for my onboard video http://www.nvidia.com/page/gpu_mobo.html

The driver already installed is 7.15.11.7515

So I get this right can anyone advise me on how to best install the PCI Express video card I have?

Try this: http://www.pcmech.com/article/how-to-install-a-video-card/

Im not sure how you installed the card, so that might of had something to do with it.

The driver already installed is 7.15.11.7515

That looks more like an IP address than a driver version :lol:. Try installing the latest ones instead: http://www.nvidia.com/object/winvista_x86_185.85_whql.html
