How do I get windows to see my graphics card?

[stolzy]

I have a second graphics card in my Mac, but windows stubbornly refuses to recognise its existence. What do I need to do to make it see the card and use it?

No idea on a MAC...you're not supposed to mess around inside those

Easy peezy on a PC




Isn't there a Mac user's forum where someone called Tarquin or Rupert will answer you immediately?

PS Windows?

You misunderstand, it works fine on the Mac (I just put it in and the monitor came on automagically), but when I boot in Windows the screen stays dark and Windows has no indication that the third monitor is plugged in or that the second graphics card is in the computer.

So how is it eazy-peazy on a PC?

Ahhhhh........

On a PC, you go to START>CONTROL PANEL>DEVICE MANAGER>DISPLAY ADAPTERS (assuming W7...it's very similar if not exactly the same with slightly different nomenclature on XP, and I have no idea what it says in W8)

If there is only one device listed, you can try adding the second ......ACTION Tab.......Scan for hardware changes.

If there are two but one has the yellow warning triangle against it, un-install the problematic one then reboot.

If only one is listed and the scan hardware changes doesn't find anything, you can either add it manuall, select it from ths list and 'point' the system at the drivers, or you can try simply uninstalling the working one and rebooting.

I have a near-top notch gaming card and a second card that drives a second and third monitor in my Windows machine....every time I update the Ge-Force drivers for the gaming card, I have to manually install the second card as the system 'forgets' it's there.

Make certain you have the very latest drivers for both cards, and also that your MOBO chipset drivers are all up to date, as that can stop the system 'finding' the second card as well

That's all on a PC running only windows though (though I do boot to linux sometimes, from a thumb drive) and I honestly don't know how the Windows system overlays the MAC OS and what the implicatios are for updating the MOBO chipset with windows specific drivers are.........I suspect it's worth double checking in case the above steps render the MAC OS un-useable

Is it the Bootcamp display driver? what's the card, are there drivers available from the manufacturer? There is no bios to tinker around with on the mac iirc, so it's going to probably be driver related or a bootcamp issue.

Is it a macbook pro with 2 adapters:-
Intel HD Graphics 4000:

Chipset Model: Intel HD Graphics 4000
Type: GPU
Bus: Built-In
VRAM (Total): 1024 MB

NVIDIA GeForce GT 650M:

Chipset Model: NVIDIA GeForce GT 650M
Type: GPU
Bus: PCIe
PCIe Lane Width: x8
VRAM (Total): 1024 MB

Under OSX only 1 of them is ever in use at a time. Googling suggests that the EFI firmware controls switching for the macbook, is this the case or do you have mac-pro with a new adapter added in?

The NVIDIA display adapter is listed in display adapters, but not the ATI Radeon HD5770. Windows spent 2 hrs looking for new hardware and found nothing.[/QUOTE]I'm downloading the drivers now - 200MB

No, its a MacPro

There is apparently no driver, but then Windows can't find the hardware either.

card is an ATI Radeon HD5770 (hardly bleeding edge)

Figured that after I googled the card...

Something to do with the order the drivers are installed in perhaps?:-

Well that's 2 hours of my life I shalln't get back.
After removing the NVIDIA drivers, rebooting, installing the ATI drivers and then the Nvidia drivers all seems to be well. To be honest, I still have no idea what I did, but thanks to the crew who got me pointed int he right direction.

I suppose it would be ungallant of me to point out that in Mac OS X, I just put the card in and the monitor lit up when I restarted the computer - no drivers, no software installation, no anything.

Thanks again.

No problem. Some people enjoy that sort of challenge, me, I'll stick to the mac.
