Unreadable symbols appearing as vertical lines on the screen while switching on the laptop. It appears for 1sec and it disappears again. Everything is normal except that. The laptop is working fine, booting is normal and no screen damage also. My laptop model is 

SP314-53N-77AJ

That is weird... I assume they disappear as soon as the Acer splash screen appears, so it's an issue with the video initialization?

Actually, it is appearing in between the Acer splash screen and the lock screen. I have no idea what video initialization means. Any solution to this problem?

OK, that's after initialization. When power is applied as you turn the system on several things happen. One is setting up the graphics chips in order for it to start making the display sow something. Once it's initialized the BIOS tells it to display the splash screen. You are getting tat far without issues... Next the system starts the Windows load. When that starts Windows displays the juggling balls which it gets started. My guess is during that time instead of the normal juggling balls it's giving you the weird display. That would be an indication Windows isn't talking nicely to the graphics chips. It might be a corrupted driver that is causing it. Try reinstalling the VGA drivers for your model.
