Windows 10: My nvidia isnt working, it appears code 45

My computer is currently running with the processor, but not with the nvidia gtx 1660 graphics card that I have, windows is fully updated and the card does not appear in the device manager unless it puts show hiddens and it reflects the following: Currently, this hardware device is not connected to the computer. Code 45. Usually I have to turn on the computer, wait for awhile and then restart for it to appear in the device manager. Please could you help me, thank you very much in advance.

Hi Escobar. I'm Greg, 10 years awarded Windows MVP, here to help you.

1) Fixes for Nvidia display driver Code 45:

2) The Display driver is so important here that merely updating it is sometimes not enough. So let's try everything possible to get it working correctly:

First make sure you have updated the Display driver from the PC or motherboard maker's Support Downloads web page for your exact model number, HP Serial Number or Dell Service Tag - from the sticker on the PC.

If necessary first remove the old driver using DDU https://www.wagnardsoft.com/content/ddu-guide-t... (not necessary with Microsoft Basic driver which is a placeholder if nothing else is available) and/or installing in Safe Mode with Networking (so you have internet), or Safe Mode, accessed by one of these methods: https://www.digitalcitizen.life/4-ways-boot-saf...

While there check also for newer chipset, BIOS/UEFI firmware (very important), network, sound, USB3 and other drivers, comparing to the ones presently installed in Device Manager reached by right clicking the Start Menu.

If this doesn't give you the latest or ideal driver for what you need, compare it to the driver offered by the Nvidia Update utility here: http://www.nvidia.com/Download/Scan.aspx?lang=e...

For Display issues one fix that is working is to Roll back or Uninstall the Driver on the Display Device > Driver tab, restart PC to reinstall driver.

You can also try older drivers in Device Manager > Display device > Driver tab > Update Driver > Browse > Let Me Pick.

Then you will know you've tried everything in addition to Windows Update drivers.

Adjust the screen resolution until it fits and looks best at Settings > System > Display.



Check for a monitor driver by expediting Windows Updates (including Optional Updates) in Settings > Update & Security > Windows Update > Check for Updates to install all Updates until no more are offered.

3) See if you can System Restore to a point before the problem started:

System Restore is your first line of defense and can take you back to a point before a problem began like a time machine. If it doesn't help then you can undo it. Read about it first in the tutorial above and then try restoring to just before this started. If System Restore is not enabled on C drive do that now so it's available in the future.

If the problem repeats or System Restore doesn't work then check which Windows Updates were installed at Settings > Update & Security > Windows Updates > Update History, uninstall them there or System Restore again, then immediately check for and block the Updates with the Hide Updates tool explained here: https://www.tenforums.com/tutorials/8280-hide-s...

If it won't work from Windows, System Restore along with Uninstall Updates can also be run from the WinRE Repair Mode or bootable media accessed by one of these methods: https://www.tenforums.com/tutorials/2294-boot-a...

Feel free to ask back any questions. Based on detailed results you post back I will have other suggestions if necessary.
