Graphics card vanished?

[󠀡󠀡]

I haven't played any games on my computer in about a week, so I'm not sure when exactly in the week this issue started, but for some reason, my graphics card seemed to have just vanished.

A few hours ago I tried opening up Overwatch to play with a friend, didn't work, so I tried opening up other games and none of them opened. I went to my NVIDIA control panel and couldn't see anything wrong, so I restarted my computer.

When I restarted my computer, NOTHING acknowledges that an NVIDIA card even existed on my computer, and I can't even access the NVIDIA control panel anymore, I get a message like "NVIDIA display settings are not available, you are not currently using a display attached to an NVIDIA GPU".

I've NEVER had any problem with my graphics card before today. It's an NVIDIA GEforce 940 MX, I know it's a pretty mediocre card, but it's been more than good enough for me.

Yes, all my drivers are updated. I really don't see what the problem is, and I don't understand why my graphics card would just disappear. Albeit I don't play on my computer as much as I used to, I still would like to be able to when I want to, and this is completely preventing me from doing anything related to gaming.

You have the Display connected to the Motherboard, not the NVIDIA GPU Card.
Power it off and connect the Display to your Card.

how does that happen? I never mess with the settings or anything like that, and the graphics card has been working perfectly fine for over a year, why would it randomly switch and connect to the motherboard?

It's a laptop.

OP, just DDU driver and reinstall it.

i guess the error is softwarerelated: reinstall the nvidia drivers and if this doesnt work, a fresh windows install with new drivers might help. if the error is hardware related the mentioned methods dont work. imo.

Oh Laptop, yes I missed that "940 MX"

Yes wipe both "Intel" and "NVIDIA" with the DDU app via Safe Mode and download and install the Drivers, reboot after each finishes.

Once completed and rebooted, re-setup NVIDIA Control Panel, setting the High Performance GPU as the Default.

Ok, let me translate all of this into The Queen's English.

Most of your PC parts use a type of software called a Driver. Drivers make everything run, they fail you won't be able use that part properly. Clearly something has gone wrong with your Nvidia Graphics Card driver, and it needs to be removed and then replaced.

The safe way to do this is by downloading an App called DDU. DDU purges all vestiges of Nvidia drivers from your system, which helps prevent any recurring problems. It's always a good idea to DDU purge your system when updating drivers, but it's absolutely necessary when cleaning off a failed/broken driver.

Find DDU through a Google search and download it. Next you'll need to put your system into Safe Mode. Click the start menu, hold down the Shift Key and click Restart. You'll see an unfamiliar window when it restarts. First click Troubleshoot, then Advanced Options, then Startup Settings, and then press F4. Your system will boot into Safe Mode.

Find DDU in Downloads and run it, having it remove all Nvidia and Intel drivers. Then Reboot your system.

Now that everything is cleaned off, follow the links Badmotha gave you to find new drivers. Download them and they'll appear in Downloads, find them there and install them.

And for your sake, use Custom Install and don't let Nvidia installed GeForce Experience! It's a bloody nuissance and you really don't want it anywhere near your PC.

thank you all though, I'll definitely try this tomorrow

good advice here but just a small thing to point out that it will only run on dedicated 940mx when plugged in not on battery and have you tried setting the power profile to "high performance"

I almost always have it plugged in (and I've noticed it runs it when on battery, until it gets to 20% or lower), and I always have it on high performance
