Dedicated Graphics Card not showing up in Device Manager / Disappearence / Not Detected [SOLVED] for ASUS TUF FX505DY

EDIT: 

The latest version of the BIOS has fixed the issue. So, the below steps are no more required to fix the issue.

Introduction:

If you have encountered a graphics card issue like the driver isn't showing up in the Device Manager, GPU disappears if the computer sits idle, graphics card isn't detected then this article helps you to fix the issue. You need to follow this procedure unless an update fixes the issue.

Reasons for the problem:

The most common reasons for the occurrence of the problem are as follows:

• Incompatible Drivers
• Graphics card isn’t properly connected
• Graphics card not being used
• Doesn't has any dedicated graphics card

[NOTE] This blog demonstrates the solution for the RadeonT RX 560X graphics card used in ASUS TUF FX505DY Laptop. You may try the solution given below, but don't blindly follow the links given in this blog as you may have different graphics card and different manufacturer.

So lets get started

Follow the instructions given below in a step-by-step process.

1. Update the Windows and BIOS

Those with AMD drivers need to update as the latest version fixes compatibility issues of the drivers and boosts the performance by 10%.

Search for the latest version of Windows [as of now 1903] and install. After the update Check for Updates settings window and proceed to upgrade the system.

Now, update the BIOS of the system. BIOS allows the motherboard to work with the new hardware. It must be updated cautiously. You can refer this link for the updation process of the BIOS.

2. Update the Graphics Card Drivers

If you have already installed the graphics card drivers uninstall it by following this process (AMD clean-up utility) or using this process (DDU). Go to the AMD website and download the auto-detect tool which installs the latest graphics card drivers (as of now 19.6.1) supported by your system. [Note] Use the custom installation process and select the latest driver to install.

3. Update/Install the AMD PSP driver

This is the most important step as this driver helps the system to recognize the graphics card properly.

After following the above 2 steps, if you navigate to the device manager you would be getting a PCI encryption/decryption controller device driver issue (due to the AMD PSP driver). So, to fix this issue you need to install the AMD PSP driver.

To install the AMD PSP driver follow this link (it redirects you to my github repo) and download the whole file and install the driver manually.

Incase, if you haven't got any PCI driver issue then the most preferable way to install the driver is by opening the setup file contained in the WT64A file as opposed to the installation procedure through Device Manager.

If these instructions hasn’t fixed the issue you need to wait for the official  update.
