Q: There is a voltage stabilizer at home, why does the computer sometimes restart

A: It should be related to the voltage stabilizer. If the adjustment range is exceeded, the voltage cannot be stabilized. It is enough to replace it with a UPS power supply. Because the UPS power supply has a battery, the battery can supply power when the voltage drops too much, so that it will not restart. However, the UPS can only be used for the computer, do not connect other peripherals. When it is unstable, the voltage is too high or too low, and the voltage stabilizer is too large to exceed the working range. It is better to bring some machine safety points. If there are more power outages, UPS power supply can be considered, because it can supply power for a short period of time.
