Hi,
I'm using a Hp 17-f067nf laptop with an Intel INTEGRATED Graphic card and an Nvidia 840m as a dedicated 3d gpu. 8go of ram, 1tb of Hdd

Long story short:
I wanted to uninstall my gpu DRIVER to roll it back and i accidentally uninstalled the gpu itself in the device manager and now it doesnt appears even after restarting the computer.

i tried rebooting, updating bios, downloading Hp Driver, multiple restart, using DDU on safe mode and uninstall the Intel gpu Driver... nothing works.
I checked the laptop entirely, opened every part that i could (except the gpu 'cause it's glued) and nothing was damaged, i even removed the cmos battery and put it back on, system restore is no longer an option cause the ddu point is no longer available.

On the other hand i've noticed in the device manager that the Intel 8 Series PCI Express Root Port #5 appears to be disconnected and when i look into the exact same computer (my brother has the exact same one) the nvidia 840m is on the #5 Port..

In the end i'm stuck with an uninstalled gpu who was working perfectly fine so far (like 10 min prior to the rollback).

-ManuI would reinstall ALL laptop drivers...chipset 1st....reboot...then all others.Okaaay,
so i've reinstalled every drivers after chipset/+reboot, i've checked and the nvidia 840m still doesnt appear, i've updated the (now newly installed) drivers and it DIDNT changed anything too. Can you share a screenshot of device manager and at Display Adapter  click on the [> to have it show whats listed here?Hi,
I'm french so the list is also in french but i think it's still understandable...


I've also sorted by connections and i've activated the hidden device:



If you have any questions just ask...

If you enter the Laptop's BIOS screens during boot, you should be able to reset them to defaults (Not optimized defaults, if the option is there). I've found instances where other users have reported success with the same type of issue (Dedicated graphics chip not visible after being uninstalled)Hi,
Unfortunatly i can only "set the bios to default" by pressing F9 and it didnt changed anything again :/

Last time i only updated the bios instead of flashing it tho, so maybe i could reset it that way?
After you press F9 to default it you press F10 to"save changes and exit"...

Otherwise nothin changes.

PS...i hope you used laptop drivers...and not Intel/nVidia ones...Yep i did save the changes

And Yes i took all of the downloads from the official HP website, i even tried with the ones backed up on the pc :/Quick update:
I managed to use a backup of the registry that was 2-3 weeks old

It brought back the hidden 3d video controller but it was still considered as "disconnected" (code 45)

Considering that it was making a lot of problems like wifi, desktop messed up i reverted back to the original registry
K so today i tried another dozen of different stuff, i re-re-flashed the bios, i did everything i knew so far...

I HATE to ask this but do you think my gpu might be dead ?
I'm more and more considering this option, which is really strange considering i was playing perfectly 5 min before i lost it.
If it's k.i.a i'm in a deep sh*t cause i dont have 1200 bucks to throw in a pc
No...backup your important data and do a clean install...

Have you put in a Help ticket at HP as of yet ? ?Yeah i had a 1tb external Hdd as a personal gift 2 weeks before the crash... i was too lazy to backup the whole thing :/
I'm gonna do some kind of cloning or so...

And yeah i asked HP, they more or less said "Hi, thanks for asking us, considering your problem contact our customer support" the thing is, their customer support isnt cheap and even if i wanted to pay it only apply to less than 3 years old product or with HpCare.Use their Forums then...Actually they told me to contact their support directly through their forum :/
