My laptop about 15 years old suddenly showed black, red, green, blue screen when I booted up, so I took it off the power and then started it again for a few months, and it ran for about 15 normal and crashed again when I booted up this colorful screen again
The operating system hard drive is probably damaged
I think it's time for a new Chromebook.
Probably defective graphics chip
No money for new
Or display in 15 years a lot can be broken.
It is not produced.
I can understand. Mine from Hp only cost 250 euro and I thought you could recommend it with a clear conscience.
