Question Msi gt70 cant install gpu driver

[halwith]

msi gt70-0nc

it came with a gtx770m which i upgraded to a gtx970m. the 970m fail last month. just got a gtx770m to reinstall to get it back up and running.
my problem is in device manager it shows the 770m as "Microsoft Basic Display Adapter" i have uninstalled the nvidia driver and uninstalled the "Microsoft Basic Display Adapter" and tried to install the nvidia driver for the 770m. it tells me no nvidia hardware found. i tried looking in uefi bios but find no option for enabling or disableing pci slots. the Microsoft Basic display Adapter is occupying pci slot 1 so i assume this is the gtx770m.
any help would be appreciated.

use DDU to uninstall drivers.

Download and install nvidia drivers from the support page of your laptop.
https://www.msi.com/Laptop/support/gt70_0nc

first pick the OS that is installed on the system, then go to drivers, then to VGA and install the third option for nvidia graphics.
If those drivers don't work then you can DDU again and try the beta drivers.

If that still doesn't work then you can try drivers directly from nvidia.

Literally that GPU is still supported with the latest WHQL drivers released from nvidia, lol. So just get the latest one which is 418.91

Thank you Qwerky Pengwen for your replay. so far no luck. i installed DDU and ran it from safemode. then tried installing the nvidia driver.
current nvidia driver 419.17 fails to install with error "no nvidia hardware detected" "not compatable with operating system" (not sure why windodws 10 64bit)
the older drivers from msi wont install because "not compatable with operating system" though that is understandable because they are for windows 8 and i upgraded to windows 10 when you could get the free upgrade.

the gpu i installed came from ebay it wasnt the origional gpu. i am wondering if there is an issue with the gpu or pci slot.
in device manager "Microsoft Basic Display Adapter" \VEN_10DE&DEV_11E0&SUBSYS_05AA1462&REV_A1\4&2e95f799&0&0008 shows an error that incorrect driver installed.

So i wanted to update this for anyone that may have to replace a gpu on thier laptop with an ebay card.
i located a vbios for msi gt70-20c
I Reflashed the vbios with NvFlash. it took a little time to find a rom. i used commands
nvflash64 --protectoff
nvflash64 --save gtx770.rom (justincase)
nvflash64 -6 (newromfilename).rom
y then y again
i was unable to run "run cmd here" due to windows 10 so i had to cd to the folder i had nvflash in. when i rebooted windows recognized the gpu an i was able to use gforce expierience to install latest driver.
