Once you know the name of your graphics card, google something like "how to update drivers" and you should get instructions. Here you'll get all the information regarding your graphics card. Here, go to the left pane & choose "Device manager".

Now a new window will open, showing all the main specifications like RAM, CPU, Windows version, etc. Right click on "This PC" or "My computer". I don't use Windows myself, but Google is always helpful: Problematically, how you do that depends very much on which graphics card you have. You can try updating your graphics driver. These were technically unsupported for a long time already, but now that 1.17 requires OpenGL 3.2 or above, you really start getting extreme issues with it. This issue is caused by using either very old hardware or a very old graphics driver. A Minecraft bug tracker expert told me that this issue is MC-218803 (which also has some other hilarious screenshots).
