Immediately after installing Windows or Ubuntu , strange glitches appear on the laptop. If you start typing something for example in the console, or in the browser, then the letters are printed, then large, then small, somehow.
As for working with the mouse: if you select a folder or file with the mouse, they are selected several at once and the selection does not go away if you cancel it, for example, by clicking on an empty area of the desktop.
I also went to Bios and there was nothing to do at all, only the signal came when you press any key, the arrow on the keyboard. And such oddities occur periodically, not every time the computer is turned on. They can occur after 2 hours of work with a laptop, or immediately after turning it on.
For viruses tested already.
