Cause of failure: Poor heat dissipation of the host, power failure and motherboard failure may all lead to automatic shutdown or automatic restart of the computer. It is common that the heat dissipation of the computer processor (cpu) is not good and the temperature is too high, which leads to the repeated restart of the computer.
Solution: Check whether the CPU fan of the computer is damaged. If it is damaged, reinstall it in time. Keep the computer working environment well ventilated. If it is a notebook, it is best to add a cooling base. Reason 2: Computer software problems.
Reason for failure: Under the default settings of win2000 or winXP, if a program does not run correctly at startup, the system will restart again, and if the problem is serious, the computer will be restarted repeatedly.
Solution: Press F8 at startup-Select Safe Mode-Enter Control Panel-System-High in System.
Level-Select "Startup and Fault Recovery", and finally remove the checkmark before "Automatic Restart" under the column of "System Fault".
Reason three: the computer power supply problem.
Cause of failure: There is an optical drive or a burner in the system. When two devices work together, the output current of the power supply will fluctuate greatly, leading to automatic restart.
Solution: Just replace the power supply with good quality.
Reason 4: Computer memory.
Fault phenomenon: The system is installed with universal large-capacity memory, which works normally at ordinary times and will automatically restart when running large-scale games.
Solution: Try to set the memory CL value to 3 or 3.5 in BIOS, and reduce the FSB bus frequency of the system appropriately; If the memory works in dual-channel mode, it is best to choose products with the same brand and speed, so as to ensure the stable operation of the system.
