Hi, I am an Independent Advisor.
Let me help you with this concern.
I understand that your computer shows horizontal lines even on the boot-up process or on the manufacturer's logo.
It is an indication that your graphics card is already failing.
To confirm this, please run a hardware diagnostics on your PC.
If you are using a Dell Desktop, please follow the instructions on this link on how to run the diagnostics.
