Memtest86 allows you to check your computer's RAM.

This solution is especially relevant when you encounter so-called Blue Screens of Death (BSoD) and problems like crashes or errors like "Instruction at address accessed memory at address. Memory cannot be read".

Memtest writes information to each memory block, and then reads it and checks for errors. In the process of testing the utility makes several passes, which allows you to identify and make a list of bad memory blocks in BadRAM format. This miracle of a programmer's thought is launched with its own bootloader, so it is not necessary to have an operating system for its operation.
