Why does the computer freeze by itself and does not respond to any commands?

Question

When you start the computer at a certain moment, it just freezes and does not respond to any requests (only reboot helps), but after it the same situation repeats more than once. This also happens when you play and just surf the information on the Internet. Help with solving the problem please!
