PC not detecting graphics card

Hello. I couldn't find an existing thread on this subject, so I am starting a new one. I recently purchased a Newegg graphics card, and I have been dealing with performance issues for several days now. I am becoming increasingly frustrated because I cannot find a solution 🙂. My motherboard is an ASUS ROG Maximus with a PCI Express slot, which should theoretically be compatible, but it isn't working. When I seat the card and connect the monitor, there is no signal, even though I can hear the standard macOS startup sounds. I have attempted various troubleshooting steps, such as connecting the monitor to the integrated graphics to access macOS and install the new drivers, but I keep encountering a "fail to load dlls. please install vga drivers of asus" error message. My BIOS settings are configured correctly. I am at a loss. My old card works perfectly; the only difference is that the old one uses DDR2 while this one uses DDR3. Could that be the issue? The system does not even recognize that the new card is seated in the slot. If anyone has encountered a similar issue or knows how to resolve this, please help 🙂

There could be a whole lot of different causes. Honestly, your best bet would be to take it to a buddy's place and try plugging it into a different rig if you can. If it acts up there too, then you've definitely got a faulty GPU on your hands, and you should just send it back to where you bought it since it's still under warranty.

So, does the PC function normally when you use a discrete graphics card instead of the integrated one? If it works fine like that, then the chip is essentially DOA (dead on arrival), and you should just file a warranty claim.

Yeah, looks like you've covered all the bases, except for testing it in a different rig. If everything runs fine with both your old card and the integrated graphics, then the problem is almost certainly that new card you just picked up. You should definitely try it out in someone else's PC before you deal with the headache of a warranty claim.

On a side note, what made you go with that specific GPU? It’s really only good for getting an image on your monitor—and honestly, your integrated graphics or even that old card could probably handle that if they were working right.

Honestly, there’s no real dilemma here—the GPU just died. If you still have the receipt, I'd say just return it

Exactly. Either swap it out for something actually useful within that same budget, or put a little more cash toward a decent card if you actually plan on gaming.

I wonder how Micro Center actually handles returns and how fast they swap things out—I mean, at a high-end retailer, you’d probably be waiting 7 to 10 days, so I doubt these guys are quite that efficient or accessible. Plus, you have to consider that almost all suppliers are doing inventory right now, and since most US computer stores follow suit, I wouldn't bother going anywhere until Thursday if I were you.
Maybe just head over there tomorrow right when they open at 9 AM and try handing it directly to someone at the door.

If you want this sorted out ASAP, I’d say just head straight to the importer to file a claim. Since we're talking about an Asus product, it's most likely MSN handling their stuff.

It doesn't necessarily mean it's broken...
Maybe you need to wipe those old graphics drivers entirely.
Plug the new card into the slot, then I would suggest resetting the BIOS on the motherboard first (hold the jumper for about 3 seconds).
Connect the monitor to the new GPU, boot straight into the BIOS, and immediately set everything back to default settings.
Then, disable the integrated graphics, save, and restart. Shut the computer down immediately, switch the monitor to the new GPU, and then boot into macOS.
If that fails, plug the monitor into the integrated graphics and follow the steps I just described.
Provided the new card isn't defective, it should boot somehow. Once it does, you can install the new drivers within macOS.

Occasionally, certain BIOS versions require an update. It shouldn't be necessary, but sometimes it happens.

If none of that works, the new card might actually be a dud. Maybe try testing it elsewhere or just return it.

Are you certain your power supply is strong enough? How are your 12V rails looking?

It's possible there's a BIOS issue or some other similar nonsense that nobody ever thinks of, though I doubt it's the power supply. You could probably run this card on your own if it were providing enough juice; it doesn't pull more than 20-30W at full load. So, it's either some glitch like the BIOS, old drivers, or it's DOA.
