Nvidia card not showing in Device Manager, Gpu not detected.

[Jacob_31]

I Recently bought Assassins Creed Syndicate on my PC. It wouldnt launch without crashing my computer, so two days ago i downgraded to nvidia 359.00 which is designed for assassins creed syndicate. Now the crashing has started again. I ran the driver installer but it said "gpu could not be detected". I went into device manager and it was not visible until i click show hidden devices. It is now visible, but it is faded like a non clickable button. Despite this it is still clickable, and says its drivers are up to date. If thats the case, then why is Geforce Experience not detecting Gpu, and why are my games low quality and lagging big time. Please help!

Pc Specs:

Alienware 14
Windows 10 Home Edition
Intel I7 Quad Core
16 Gigabytes RAM
Nvidia 750m Graphics Card

Hi,

Please do try these troubleshooting steps that may help.
- Start by doing a hard reset, remove the battery and AC adapter then press and hold the power button for 20 seconds.
- Next is to do a clean install install of the graphics card driver.
- Please refer to this link on how to do the clean install of the graphics card.
- http://www.tomshardware.com/faq/id-2767677/clean-graphics-driver-install-windows.html
- Once you've successfully installed the graphics card driver, do check Device Manager again and see if it will be listed normally.
- If all these will not work you may need to do a clean install of Windows first because if after reformatting your PC and the same problem will persist that means it's a graphics card issue. 🙁

I went through a very similar experience, It was surreal. Both my Geforce titans had disappeared from the device manager, and 2 of my three monitors were not working. The center monitor was working but the resolution was totally off. These are the moments when your spine chills, and panic sets in.
The computer technicians said it could be the ram or mother board or power supply, Or simply malaware. I was desperate. The PC seemed to be working ok but anything graphic related was out. I reinstalled Nvidia drivers to no avail.
The next day took my PC to the tech, who booted it up and the machine ran perfectly (Win7). Both my titan cards were back in the display manager. WOW. Although relieved, I felt i was in a bad dream, How is this possible?
I went back home, plugged in my PC to the APC back up UPS, powered up win 7, and the same exact thing..the titans has vanished!! My screen resolution looked horrible.
In an act of desperation, I look to the floor and see the UPC sitting there, an APC PRO 1000.
It seemed to be working correctly...surely it can't be the UPC?
It turned out it was the UPC. The UPC had gone bad, but with no warning messages whatsoever. In turn it was not powering up the power supply correctly which in turn had made my two Titans disappear and my resolution screw up.
As far fetched as this story is, I was very lucky it was only the UPC and not my two titans or motherboard.

found a solution for mine, i notice that my nvidia geforce gt 640m didnt even show up in bios so as in the device manager.so i update my bios, viola! and its there!in the bios! i opened device manager, and then theres two gpu, without any name or driver, just stated as 'standard vga adapter'. then i install intel hd graphic and my nvidia driver...then i spend hours gaming

DDU and countless hours of trying different software and manually trying to install drivers for my nvidia graphics card and finally found something that actually worked.

All I did was uninstall windows updates from around the time the problem started happening. That's it. Solved.
