Hi, I have recently changed my processor and motherboard from AMD to Intel. Everything is plugged in correctly and powered up and on board graphics are working fine, but my GPU is not being detected and thus I cannot install the drivers (as NVIDEA wants the card plugged in to do so).

The card worked fine before and the only changes are Processor, Mobo, ram and cooler.

I have not wiped my drive.

Spec:

I7700k (H80i V2 liquid cooling)
msi z270 gaming m6 ac
2x 8gb corasair DDR4 3000Mhz
Corsair CP-9020093-UK 850 W
GTX 1080Ti

Runs on win 10

anything more info needed just give me a shout.

Thanks in advance

Hi,
I'm sorry for my late response.
How is it, does it works?

If not, I looked att Your mobo MSI z270 gaming m6 ac a it seems that it has an inbuilt graphics port (hdmi) + a DispalyPort and I suggest that You unplug the graphics card fom the mobo, instead connect the monitor directly to the Hdmi-port or the Displayport on the mobo.

Just to see if you get any picture on the monitor and to see if the computer works att all.
For a start.

Next, mount the graphics card on the second PCI-E x16 slot from the CPU - not the first - and make sure it is well seated into the slot, connect the 12V PCIE power connectors from the power supply and restart and test.

Caution: some mobo pcie slots has (or have in english?) a lock, like a tiny...

Hi,

1. First of all make sure, really sure that all cables are seated correctly and attached t to the right thing, even if you think you have checked this.

2. Make sure that the graphics card is mounted in the first PCIE slot closest to the cpu.

3. Make sure that the graphics card are really seated firmly into the motherboards pcie slot, and not in any way is titling or what so ever.

4. Make sure that the graphics card 12V power supply connectors, which comes from the power supply is really and firmly connected to the graphics card.
Not only that, make sure the power connector/s is at the correct position. Press on them to make sure.

5. All other connectors must be checked, from the power supply to data connectors and be meticulous about this.
make a list and check everything.

I Know, but do this carefully, then we can take the next step - if necessary
Best Regards from Sweden

Caution: some mobo pcie slots has (or have in english?) a lock, like a tiny plastic "tab" at the bottom rear end and it sometimes must be moved sideways to be able to unlock, so that You can lift the card upwards. Important to check this if You find that the card is somewhat stuck into the moobos pcie slot.
Not all mobos have this, but just for information.


Sorry for my poor english.

Calvin_7 is correct. The motherboard drivers for the USB, Sata, pcie etc are different for different mobo's and different vendors. Windows had some basic, very generic drivers for these, but they don't work to full expectations, just enough usually to get the job done.

Your registry is set to look for those particular chipsets on the old motherboard at the old motherboard addresses. If you then add the new mobo drivers, you can and probably do, get conflicts, which you may not notice, but boot takes twice as long as it should.

To go through system32 and syswow64 hunting down the old drivers, removing all of them for the old mobo and then going through the registry and removing all traces of the old addressing is an extremely time consuming process, and you might not get all of them as the names can be somewhat misleading.

The simplest and easiest way is to reinstall windows, which resets the registry from blank, and removes any and all mon-windows drivers from the system folders. Then just add your mobo chipset drivers for the new mobo and the gpu should be recognized.
