The computer restarted while playing with it. Is it because of insufficient voltage? The keyboards all have lights.

When your computer restarted, what were you doing on the computer? Can you tell me? I will answer you more accurately based on what you said.

Please describe in detail the performance of your computer before restarting and your operations. It may be that these operations caused the restart. If you have any questions, please ask me (I will answer again based on the information you provided) you).

Generally, restarts are caused by incorrect operations. Remember not to perform operations that are likely to cause restarts. Do not operate the computer at full load. That is, when you are playing games, watching videos, downloading, or browsing web pages, it is most likely to restart, crash, or blue screen when doing other operations. Therefore, do not operate the computer while playing games, watching videos, downloading, or browsing web pages. Working on something else.

No matter what you are doing, as soon as there is any sign of lag, immediately stop the operation at hand and exit the trial, so that it will not restart. If the situation persists, stop playing or watching.

In terms of hardware, the temperature of the CPU and other hardware is too high, there are too few memory cards, the hard disk has bad sectors, the voltage is unstable, and if there is, it is caused by inappropriate hardware.

90% of restarts are caused by improper operation of the computer. Cards are the root cause of restarts. If you do not operate the card easily, restarts will be avoided or less likely to occur.
