Vertical lines on your computer screen can be caused by hardware failures, loose cable connections, or driver issues. To troubleshoot, first, try reconnecting and checking all cables for damage.

If lines continue to appear, it might indicate a hardware issue with the screen itself, requiring professional repair or replacement. Always ensure your system's software is up to date as a preventative measure.
