Memory error in windows, what to do?

Question

Windows

Greetings,
I made a dual boot on a laptop - win10 / ubuntu, and everything would be fine, but Windows periodically crashes with a memory management error. It was checked by the built-in memtest - it sends to check the hardware. At the same time, ubuntu works fine and the memtester did not reveal any errors.
Laptop - ideapad 710s, soldered memory, updated drivers, no viruses. Winda is a pirate, but the second one with such a problem.

Answer 1

Boot from a bootable (CD, flash, ...)
memtest 86
or
memtest 86+
