Ram error or configuration error?

I have 8 gigabytes of RAM in one of my laptops, but the control panel says 8GB RAM 2 can be used and I don't get the graphics card driver installed, nor the network driver. Today I did USB tethering with my mobile phone. I would like to play Minecraft or Among Us with it, but without RAM Internet and drivers that is not possible.

RAM: Samsung 2x 4GB DDR3

Graphics card: Nvidia GeForce GTX 520

System Windows 7 32 bit

Storage 500GB HDD from Samsung

System Windows 7 32 bit

Here is the mistake. 32 bits are not enough to use the 8GB RAM. You need the 64 bit version of Windows.

Correct graphics card driver used? What is entered in the BIOS?

First install Win10. Then most of your problems should have been resolved.

Windows 10 is not stable and Windows 7 is still getting updates

What if the laptop is 32 bit based?

Wrong and no. Where did you get this information from?

Windows 7 will receive security updates from Microsoft until 2023.
