  1. Nvidia GPU Not Working. Error Code 45


    Hello!


    While i was downloading a new dirver update around 4th of may, both my screens just went black. I restarted the pc but when the screen didnt recive any signals after 5 minutes i realised something was wrong. I tried plugging in one of my screens into the motherboard insted if my nvidia GTX 1080. The screen turend on and i could log inn.

    The grafics card didnt show in the devicemanager, when i displayed ''show hidden files'', it popped up and under inspections it said ''Currently, this hardware device is not connected to the computer. code 45''

    ''to fix this problem, reconnect this hardware device to the computer.''


    I found a fix for this problem by going into biosUEFI bios utility version 2.19.1269>advanced>System Agent SA Configuration>Grafics configuration>Primary Display changing this from auto to PCIE.

    This worked, the grafics card did work again. The screens shut down a could of more times but it was an easy fix so i stuck with it.


    The real problem came today about a month later, 16.06.2020, the fix dosen't work anymore. Its the same thing that happened last time, what to do?



    Thank you so mutch in advance.

    :)

    Nvidia GPU Error Code 45

    I have the same problem.

    I did the steps, but it is still hidden in device manager and still has CODE 45.

    Can you please help me..

    I have aspire 5750G with NVIDIA Geforce GT 540m.

    Thanks.

    Nvidia GPU Error Code 45 Laptop

    Hello,

    I am having some problems with my laptop. First, when I try to install any Nvidia drivers for my RTX 2070, it says that the GPU is not supported. When I look in Device Manager, it says that the GPU, which is internally in the computer, is not connected to
    the laptop and gives Code 45. When I look at the control center, that came with the computer, it says the GPU temperature is 0 and usage is also 0%.

    Please help,

    Hi Chris,

    The error code you've received is only used to provide the status of the device. To isolate your concern, we suggest that you roll back to the older driver and check if it helps to resolve the issue. To do this, please follow the steps listed below:

    • Press Windows Key + X then select Device Manager from the list.
    • Locate your graphics driver and double-click to open the Properties
      option.
    • Go to the Driver tab and click the Roll Back Driver button. Click
      OK.
    Let us know if you have other concerns that we can assist you with.
