Analysis and elimination of frequent crash failures caused by insufficient CPU power supply

Recently the computer has always crashed, my CPU model is Intel Celeron, the core voltage by default of 1.5V, after the boot into the BIOS check to see the CPU operating voltage is only 1.2V. The computer has always been relatively stable, how can i solve this computer failure?

[Analysis and exclusion]

From the above analysis, Because the default operating voltage of the CPU is 1.475V, today, only 1.2V work voltage, so the reason for the computer often die is the CPU is not enough to cause, this situation is likely because of the motherboard components aging, resulting in the power supply part of the voltage is low, the CPU naturally can not work, the crash is inevitable. Like overclocking, the CPU will not be very stable after the lifting frequency, some need to increase the voltage to stabilize the higher frequency, this reason, in fact, a considerable part of the computer failures and power-related.

There are many reasons for the lack of CPU power supply, first of all, we should check whether the power of the machine match, the author encountered many machines can not start or instability of the reason is directly caused by the power supply. Check the power before we should first consider whether the computer has been added cards and other accessories, some brand-name machine power and the total power of the system is exactly the same, add a new board will likely cause power supply shortage. Therefore, if you have to add new equipment to take down after the equipment to try, if not, then we must consider the stability of mains power supply, in some places the power supply instability will also appear such problems, if it is possible to install a voltage regulator. In addition, the installation of too many USB peripherals will consume a lot of power and may also cause system instability.

If the power supply is not a problem, then the problem will generally appear on the motherboard, then only check the motherboard if there is damage to the capacitor, if the damage to replace the motherboard.
