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).

I 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 :/
-
Their forum has free support and someone there might be able to share free help who is more familiar with the specific model. From my experience with their support they ask some questions and verify a few things and then 99% of the time its suggested that you backup your data to an external device or media and then reinstall the OS clean after wiping all old data and then installing drivers etc. *Note: If you have the recovery media for your computer you dont need to mess with drivers as for it will push a clean from factory install of the OS and all software and drivers bundled. So if its corruption in the build data this corrects this. Then from their its best to make a full backup and then update nvidia drivers to latest if there are games that require a driver update to correct for a bug or something.
As Patio suggested earlier though, I agree that important data should be backed up and then totally wipe the drive and install the OS and drivers fresh. Then if your in the same situation that is when i would refer to their forum, this way when you post to their forum if it doesnt correct for this you have eliminated a great deal of potential problems and may be closer to a solution.
-
Yeah i think i'm gonna have to do a clean Os... but i keep getting more and more problems as many programs dont detect the nvidia card anymore.
It's really bothering me considering the amount of software that i will have to reinstall tho... at least i hope i can backup my personal data.
In this case, i have a question is there any program that allow you to clone the internal Hdd and fully recover it in case of problems ?
-
Yes...however if you clone it it'll carry the same issues you have now...
I use and recommend Acronis True Image for this...not Free...
Best Free alternatives are Macrium Reflect...or Easus ToDo.
-
Thx ^^
I'm planning on cloning but just for storage reason, with cloning i'll be able to return to my previously deleted files... if it solves anything of course :/
-
What app you thinkin about for clonin ? ?
I use and recommend Acronis True Image...not free though.
Best Free choices are Easus ToDo...and Macrium Reflect...
Best of Luck...let us know.
-
Hey,
so i've downloaded macrium effect.
Right now the cloning is launched since 20 min and i'm hoping it will be finished soon.
After this i'm planning on doing a refresh to see if it can solve my original problem, if not i'm gonna have to do a hard or factory reset i dunno.
What scares me the most is that what will happend if nothing works, but that's an other story...
-
Okay so everything is cloned on my other HDD and is (apparently) perfectly in place.
My question now is: Can i revert (as a last solution of course) revert back and clone back again what i just copied on my external Hdd to my internal one?
Thx again btw, i'm going to reset my pc as soon as you'll answer ^^

Hey!
So after 3hours of getting my pc back to factory state and an hour of reinstalling everything... well nothing happend 😭
My Nvidia 840m seems definetly dead 😭 it doesnt appear in the device manager and the nvidia setup doesnt detect it
