Diamond R7 250 graphics card isn't dectected on Windows 7.

[Dex Luther]

So my computer has Radeon 6800 HD graphics card. Since it's the holiday season and a saw a Radeon R7 250 on sale, I figured why not upgrade it?

I got home and did the standard shpeel. Uninstalled the drivers (I know both cards would use the same ones, but I figured there was no harm in doing things properly anyways). Turned my computer off, removed the old card, installed the new card, booted the PC.

The result: Black screen.

I plugged the monitor into the onbloard VGA, logged into windows, installed the drivers, Turned my computer back off, plugged my monitor from the onboard VGA to the GPU's VGA and booted up again.

The result: Black Screen.

Plugged the monitor back into the onboard VGA, logged into windows, opened the device manager, and noticed that the Standard Windows Display is the only option there. Scanned for Hardware Changes. No change.

Restarted my PC, went into the BIOS, but there doesn't seem to be an option to disable the onboard display.

I've tried re-installing the GPU's drivers, I've tried clean installs using CCleaner and Display Driver Unintsall. One of my first thoughts was also that I hadn't plugged in the wires from my PSU, but the Diamond Radeon R7 250 doesn't seem to have any connectors for it.

I'm at a loss. I don't know what to try next, or even what I'm missing. The only other thing I can think of is that it's because it's a Dell XPS 8300, and that maybe there's something preventing hardware upgrades on the machine, which is something I've heard is a common thing when it comes to pre-built machines.

I may be wrong but that has to have a 6 pin power connector on it somewhere if it's a 2g DDR5,.

Thanks for your quick reply. I thought the same thing, but looked everywhere and couldn't find anything.

There's a happy ending to the story at least.

I was so desperate and pulling my hair out that as a last ditch effort before putting my old GPU back in, I turned my computer back off, and pulled the new GPU out. I looked all over it for any kind of connector, tabs or defects I might have missed. Finding nothing I putt it back in. The strange thing this time is that there was a sort of loud click sound. I don't know what it was as I had cleaned the slot and made sure the card was properly seated the first time.

I plugged the monitor into the card, turn the computer on, and almost cried for joy when I saw the beautiful sight of a boot logo appear on screen.

Moral of the story: Even if you're absolutely sure it's in right, you can never go wrong with trying to reseat the card anyways.
