Windows 10: Random Blue And Pink Things Appear On My Computer At Startup

For some reason, ever since 2/9/2021, my computer has been glitching. It first started in Microsoft Edge Chromium. Then, when I opened my computer today, it happened on login. After that, the logos start going static.

My Windows Version:





I can't make a screenshot of the screen lagging, because if I use Snipping Tool or Snip & Sketch, it looks fine.

horizontal pink and blue lines

I have horizontal pink and blue lines starting at the top of my touch screen at start up. The only way to "fix" the problem is to use the touchscreen and restart the computer. I can see a small portion of the desktop at the top of the screen and it appears
normal. Any suggestions?

 

Startup Blue Screen

Hi Jon,

Startup blue screen error(s) can occur if a problem causes your PC to shut down or restart unexpectedly. It could be due to the following:

• Outdated device software drivers
• Corrupted Windows update system files
• Software/Security conflicts

We would like to know some information:

• Did you get any blue screen stop error codes?
• Have you tried booting in Safe mode?

We suggest that you check this
article about troubleshooting blue screen errors and follow the troubleshooting steps provided there.

We will wait for your response
