Which graphics card will my motherboard support?

hardware Graphics card not recognized - what now?


Seldom, but it does happen: you install your new graphics card or install a new system, but Windows does not recognize it. You will then still see an image, but 3D acceleration and other features of the card are left out, Windows feeds the monitor in emergency mode, so to speak. Here you will find various solutions that should cover 90 percent of all cases.

The picture is there, isn't it ?!

First of all, a word about the problem itself: If the graphics card is not recognized, the obvious idea is that you can no longer see anything on the monitor - and yes, that can also happen. But that is not the essence of the article, because this error occurs extremely rarely and can actually have only two causes: Either the cable, the monitor or the graphics card is defective - the only thing that helps is to check with other hardware. Or: Many PCs have an onboard graphics card, a "small" card that is installed directly on the mainboard. This also has its own connection - the monitor cable must of course be plugged into the new card. Yes, it sounds stupid, but incorrectly plugged in cables are actually one of the biggest sources of error. Ask the admin at the employer about tangled cables and take your time with the stories ...

However, this is about errors for which a picture can still be seen. The point is usually that the card is not recognized and Windows does not address it as "Card XY", but as a standard card - and thus leaves out the actual features of the card.

Problem 1: driver does not work

Your first attempt should be a simple one Driver update apply because it causes the least effort and often works:

  1. Search for and start the "Device manager".
  2. Fold the point "graphic card" on.
  3. Open the context menu of the graphics card entry via Right click and choose "Update driver".

Even if that doesn't work, you should still address the driver as the cause. This time a complete reinstallation follows, including previous deinstallation of old graphics card software:

  1. Call up the context menu of the graphics card in the Device Manager again and this time select "Uninstall".
  2. Open the program management under "Control Panel / Programs and Features".
  3. Find all tools from a previous graphics card via "nvidia"or"ati"and uninstall them as well.
  4. Get the right one Ati or Nvidia drivers from the respective homepage.
  5. To install The driver and restart Windows when finished.

Problem 2: Second graphics card installed

It is possible, if not very likely, that a second card is installed - more precisely, a second graphics card driver. Two installed graphics cards are not really intended under Windows, so one must be uninstalled again:

  1. Open the Device manager and open the point again "graphic card".
  2. If you find two entries here, first identify the card that Not the right one is.
  3. Open that Wrong card context menu and uninstall You this.
  4. Restart Windows.
  5. If the problem is still not resolved, try again with the solutions to the driver problem.

Problem 3: Incorrect PCI setting

With Windows 10, many users initially reported problems with the PCI slot in which the graphics card is inserted. These are features of PCI Express that do not work correctly. The solution to the problem: The new features are not addressed, only the "legacy versions", ie the standard functions. "Legacy" usually means something like "old-established, is still supported" in the IT world.

  1. Open a terminal using the keys [Windows] + [R] and the command "cmd".
  2. Enter the command "bcdedit / set pciexpress forcedisable" a.
  3. Restart the computer.

"bcedit" stands for "Boot Configuration Editor", which here sets the "pciexpress" feature to the value "forcedisable".

Problem 4: motherboard driver

If all these graphics card-specific measures do not help, you should try another driver update and bring your motherboard software up to date. To do this, you first need Manufacturer and model name of your motherboard. The easiest option is probably the free program CPU-Z:

  1. start CPU-Z and look in the tab "Mainboard"after the model name.
  2. Check your computer for one Update / management tool from this manufacturer. If available: continue with point 4.
  3. Get the Update / management software for your motherboard from the manufacturer and install them.
  4. Start the mainboard tool and run a Update by. How exactly then depends on the manufacturer.
  5. Restart the PC.

Problem 5: card hardware

As mentioned briefly above, it is of course also possible that you simply cannot see anything. In this case, you should take the following steps until something works - the effort increases:

  1. Check whether the connectors on the monitor and computer are properly seated - check, do not guess!
  2. Check whether the connector on the PC is really in the graphics card, not in the graphics connector on the mainboard.
  3. If the graphics card has several connections, switch through once to test.
  4. Open the computer and see whether the card is really seated in the slot and is locked into place (there is a small lever on the inside of the slot that engages when the card is correctly inserted).
  5. Check whether the graphics card has two separate power connections and whether both are really connected - it fluctuates from card to card.
  6. Swap the connection cable between graphics card and monitor, try alternative connections if necessary (HDMI, DVI, Display Port).
  7. Test the computer on a different monitor, for example your television.
  8. If at all possible, test the graphics card in another computer or a different graphics card in this computer.
  9. If nothing works: Uninstall the card and all drivers, connect the monitor to the connection on the mainboard and restart the computer. If everything works now, the card is probably simply gone and you should send it in.

We left out one little thing, namely the human factor. It shouldn't be, but of course it can happen: The graphics card simply does not fit the mainboard or, in very exotic cases, not the Windows version. On the hardware side, a card should actually work if it fits into the slot - but there have been stranger things in the IT world. Likewise, all Windows versions since Vista should actually work, but just take a look at the cardboard box of the graphics card, it should be there. Anyone who actually still uses Windows XP (yes, it still exists ...) will probably have to live with the fact that it doesn't work.
