All of the sudden, vertical and Horizontal blinking colored lines appeared on My Mac Pro. Tried to get rid of them . Nothing seem to work?
If this persists after a restart, you likely have a Hardware issue.
As an experiment and a test for a work-around, you could use an adapter to connect to your TV set or external display.
Otherwise, you should arrange for service.

if you have the 42-lb silver tower, its graphics cards may have multiple ports available, and you could consider testing with a different port.
If it is still using the original graphics card, they get hot and do not age well -- you may need to upgrade it.
what model-year Mac Pro? Do you know the graphics card make&model? what MacOS version?
MacBook Pro (13-inch, 2018, Four Thunderbolt 3 Ports)
