Windows 10: Random lines on the screen

So i was using my computer working all perfectly fine. I turn off the computer, perfectly fine. 1 hour later my brother goes to play on it but there are green horizontal dots / lines appearing on "dell" screen so he turns it off and waits a week to see if that fixes it. One week later it hasn't changed but I make it to the home screen, now the lines have gone horizontal, and when I move my mouse ontop of them they disappear. Ignoring it I log on. But then the computer seems to go into overdrive sounding 4x times louder than I have ever head it and the screen is extremely zoomed in so I turn it

win 10 update leaves vertical pink line on screen

today i applied latest win 10 update and now i have a vertical pink line on screen, it remains on every screen. i have tried these fixes

Step 1: I suggest you to run SFC scan,
System File Checkeris a utility in Windows that allows users to scan for corruptions in Windows system files and restore corrupted files.

Follow the below steps:

• Right click on the Start button, click on
  Command Prompt (Admin).
• Type “sfc /scannow” without the quotes and hit
  Enter.
• After the scan, restart the computer and check for the issue.

Step 2: Also, I suggest you to update the display drivers and check.

Steps to Update the Display Adapter driver.

• Press Windows key + Xkey when you are at desktop.
• Select Device Manager.
• Expand Display Adapter.
• Right on the Display Adapter and click on
  Update driver software

BUT i still have the line on screen.
