XFX Radeon 4890 1GB 256mb

[Giambatista]

I built a new pc for christmas. I got the XFX Radeon 4890 1GB 256mb for my video card.

I hooked that card up to my new ASUS M4a785TD-V mobo.

I haven't been able to get the video card to notice the presence of my new monitor; Samsung Syncmaster 2233RZ.

I installed the card into the PCI16_1 initially. When it wouldn't pickup my monitor i moved it to the PCI16_2 slot, but that didn't work either. My mobo appears to be working as the fan runs, and my dvd player which is connected to the mobo via sata works fine. My video card appears to be working also as the fan is running. So it doesn't appear that either product got fried in the install process. I've tried all the basic trouble shooting techniques I could think of.

Any suggestions?

It might be that your onboard video chipset is activated instead of your dedicated card. You might need to enter the bios to set PCIe as your default adapter. This is of course based on the assumption that you hooked the screen cable to the card outputs not the motherboard ones.

And also what you could do is through the OS disable the onboard graphics through device manager, and then install your new card.

Also Rolli had it right with also changing the Bios settings.
Those 2 things should fix your problem, since i had a similar problem on a old computer.

The problem with both those solutions is that I have no way of seeing anything on my screen, so i can't navigate to the bios or anywhere else. Nothing will show up on my new monitor or my old monitor.

Try plugging into your onboard and see if that works.

 

[Giambatista]

Are you suggesting plugging my monitor straight into the mobo instead of the video card? Or am I misunderstanding you?

 

[rolli59]

yes if that is active it should display picture and allow you to do the bios settings.

 

[Giambatista]

ok cool, i'll try that out tonight

I hooked it directly into my mobo and got the exact same results; nothing. Still no monitor display or anything. I've no idea what the problem is.

remove the video card, pull the motherboard battery for 30 seconds, put it back in, attach a known working monitor directly to the motherboard's video out, if it still doesnt work your mobo has an issue and needs to be RMA'd.

 

[Giambatista]

I'm starting to think the mobo does have a problem, even though its fan is running, my mouse/keyboard don't seem to be getting power either.

 

[Giambatista]

I just pulled the mobo battery and tried the monitor again; nada. Gonna be pretty bummed if I have to send this p0s back to newegg

 

[Giambatista]

any other possible solutions?

 

[rolli59]

You did try taking out the 4890 when hooked up to the mobo! Some boards switch the integrated of if they recognize another GPU installed.

 

[Giambatista]

yes, i removed the vid card when i did the direct connect to the mobo

It really looks like you have a faulty motherboard. It happens.
