Blank Screen After Upgrading Graphics Card.

erickj92 · 17th May 2009, 10:34 PM

Recently I upgraded my systems graphics card from the 512 MB version of this "9400 GT 1024MB PCIe" to this new card here "9800 GT 512MB PCIe". Oddly now when I start it up I get a completely blank screen, and hear no POST beep. When I pull out the card, and use the onboard graphics my computer works fine. Also, the 9400 model worked just fine in my computer. Why would this new model not be working correctly? Any help would be greatly appreciated.

System Specs:

3 GB RAM
2.8 GHz Dual Core CPU
Biostar Mobo
GeForce 9800 GT

Some things to consider...

Is your power supply able to provide enough current?
Is the card is seated properly?
Try to boot with NO graphics card AND onboard turned OFF, do you get any beeps?
Maybe try uninstalling the 9400 card before re-starting the machine with 9800.
OR
Does the card work in a different machine? If not, then I suspect the worst.

Well I did consider the power supply to be an issue. It is only 250 watts, but it has powered the other GPU's just fine, which made me not think it was the psu. Is there a way to make for sure it is the psu?

On a side note: Is there a chance my mobo doesn't support the new GDDR3 the 9800 has, when the 9400 had DDR2?

Also, when I booted up the machine with NO PCI card, using the onbaord, I saw only the onboard GPU in Device Manager in Windows XP.

Thanks for your responce.

most likely PSU, did you connect the PCI-E power to the graphic card?

"did you connect the PCI-E power to the graphic card?"

I've seen that asked many times, but oddly I don't have a PCI-E power cable. I know the manual speaks of it, being a 6 or a 4 pin, but I don't have a slot for a cable on my video card. Am I overlooking a major detail?

Yes, it's a must to connect PCI Express power connector.

My video card has no spot for a power chord to connect to, though. The only thing my card has is a power chord going from the card to the cooling fan. There is one other connection, but it's only a 2-pin plug in, and by the looks of the manual that is for HD-Audio. Is there maybe something else that I need to hook up? If so, why did my old card work without this?

Edit: More specifically, this is my card: www3.pny.com/9800-GT-512MB-PCIe-P2814C402.aspx

That's because your previous card is a lower end card which isn't as power consuming.

The power connector is definitely there, all 9800 series cards do. It's usually located at the top right area of the card, when looking at the fan. It's a black connector with 6 pins connection.

I'm not seeing a 6-pin connector. Here is images of my card: GPU pictures by erickj922 - Photobucket if you would please take a look and tell me what exactly on the card I need.

now thats the first 9800GT without a 6-pin power.
did you try the card on someone else's computer?
it could be that there isnt enough power to boot up the card.. hmm
