Red, blue and white stripes on start screen

I noticed that more or less 1 month ago and my computer can run normally but as I will finish to pay my PC this month and I don't know how to explain what is going on to my PC to look for my support (japanese), I'm trying to understand first and see if I can solve it by myself.

The video was uploaded on you tube and I hope sb can help me, pls...
Thank you so much.

Hi,

Start by uninstalling/reinstall the graphics driver of your PC.
- Go to Device Manager and uninstall the graphics driver.
- Open Programs and Features and uninstall anything related to your graphics card.
- Download and install the latest driver from the manufacturer site.
NVIDIA: http://www.nvidia.com/download/index.aspx
AMD: http://support.amd.com/en-us/download
Intel: https://downloadcenter.intel.com/
- Once installed reboot your PC for all the changes to take effect.
- Observe your PC once the driver has been installed.
- If the same problem persist try disabling FastBoot in Power Options.
