I have long had the problem that my laptop "crashes" for no reason. It appears a black background then the noise comes as if you plug in a USB device and it appears a colorful square. This is usually so 5 minutes then disappears the colorful square, my laptop goes up but then it is extremely slow. Even if I want to open my files then it takes about 10 minutes.

Does anyone have a solution for?

Thanks for any reply!

Ps: I have an Acer Aspire E 17

Intel Core i7-5500U

Nvidia GeForce 940M

Is that synonymous in the BIOS?

Please try.

Otherwise, the path of least resistance. Back up data, reinstall Windows. With Windows 10 approx. 15 min. So no huge effort.
