Thinker i35 suddenly turn rainbow screen

My Thinker i35 keeps turning into rainbow screen after just a bit of usage

I removed the installed M.2 SSD and booted from a USB Live Ubuntu thumb drive and the same thing happens

The same thing happens if I booted from a USB Live Android thumb drive

The exact point at which the rainbow screen appears may vary slightly from occasion to occasion

It almost always appears at the point when I connect to the wifi

I just don’t know whether it is a BIOS or UEFI virus or a hardware problem

Any advice would be most appreciated, thank you

You can try an external monitor and see the output to judge whether it is a problem with the display screen or the display cable.

Yes I already tried that, when the laptop screen goes berserk, the external display does blank at the same time

So I think the LCD screen is fine
