Sorry it doesn't work for you :(
Try to find out which graphics card you have (probably Nvidia (green icon) or Radeon (red icon)). If you google "How can I find out which graphics card I have in my PC" there should be a step by step guide for you to figure it out.
Once you know which model you have, you google your graphics cards name and the word "driver". There you should be able to find the newest software update for your card.
I'm super bad with this stuff as well, but updating drivers is never a bad idea :)
