First of all, if the CPU is broken, the computer will definitely not turn on.
Secondly, are you saying that you pressed the power button, but there was no response at all? The fan doesn't turn either, does it? Obviously, this is not yet the CPU step, according to your description, it should be a problem with the power supply.
Solution:1You open the chassis directly, in the lower right corner, find an interface connected to the host switch, called PW-SW, dial it out, and then expose the two connectors, you short-circuit them with metal to see if there is a response (here is a suspicion that there is a problem with the switch), if there is, the switch is broken, in other words, if it is still not, it is the power supply is broken.
2.Remove the power cord of your hard drive, and then turn it on to see if there is any response, sometimes the hard drive is short-circuited, and it can't be turned on. If there is a response, there is a problem with the hard disk, and you need to maintain and replace the hard disk, and at the same time, you must also change the power supply, because this is caused by the power supply, and you don't want to replace the hard disk and break it immediately.
3.It depends on the situation, your CPU should be good, even if you remove the CPU, the motherboard's fan will react.

Unplugging the CPU host can also turn on the fan. Open the chassis and plug in the cables. The CPU can't be broken, it should be a boot switch and power supply problem.
Then plug the line back in. If it doesn't work, the first thing is the power supply. Others require further testing.
Is the CPU out of warranty? Boxed is generally three years old, provided that the appearance is not damaged.
-
The CPU can be started if the host is broken, but it will never enter the system, the screen will always be black, and you can hear the sound of the case, the situation you said should be a motherboard problem, or a power supply problem.
-
If the power supply is not affected, hurry up and buy a new CPU or a second-hand one, the CPU will not start if it is broken.
-
The CPU is equivalent to the human brain and heart, how can the computer still start up when the CPU is broken?
-
The CPU fan is used to cool the CPU, if it is broken, that is, it does not rotate, the computer can start, but after using it for a while, it will crash, or even burn the CPU, that is, the front indicator light is on. The power supply is the power guarantee of the whole host, and its function: step-down and conversion, to prevent external current impact.
If the power supply is broken, the computer won't boot....That is, it doesn't light up.
-
When the CPU is broken, it can't boot into the system and BIOS, and it doesn't show at all; If the motherboard is broken, there will be a buzzer that beeps.
Don't plug in all other parts, don't plug in memory, just plug in the CPU, turn on, see if there is a long beep alarm, if not, the motherboard is more likely to be broken. If there is an alarm, the probability of CPU being bad is greater, under normal circumstances, the possibility of CPU being bad is very small, and the possibility of motherboard being bad is relatively large, so your host is likely to be motherboard bad.

Summary. Excuse me: Will the CPU power supply of the motherboard be affected by the burning?
Hello dear, the CPU is fully loaded, the natural power will increase, you say that there is a problem with the power supply module, and suddenly there will be a lack of power supply. In addition, it is quite rare to be able to occupy 100% of CPUs now. Are you sure it's not your CPU low end that's causing it?
In recent years, new CPUs have the function of intelligent frequency reduction to prevent CPU overload and failure, so as to protect the hardware. Hope it helps. Wishing you a happy life and good health!
Excuse me: Will the CPU power supply of the motherboard be affected by the burning?
How much does it cost to fix it.

Hello dear, 800-1000
The CPU power supply is burned, do you want to replace the power supply chip?
It must be replaced with a motherboard, and the repair is not lower than the motherboard, and the quality has not been replaced with a second-hand that has not been repaired. Even if the graphics card is broken, it's no problem. The graphics card is on the motherboard

Whether the power supply of the computer host is damaged or not is accurately detected Steps:
1. Press the power button to see if the power fan is rotating. If it can't be rotated, then it can be removed for troubleshooting.
2. In order to accurately judge whether it is a power failure, after removing the power supply, you can use any conductor to connect the green wire with the black wire, and see if it rotates after connection. Or use a multimeter to test the voltage between the green and black wires (the voltage should be about 5V at this point). If the voltage value is too low or none, then the power failure problem can be directly determined.
3. If the above method is tried (the power supply fan can rotate, and the voltage value is also about 5V), then or the power supply is normal, but in order to accurately judge whether it is really bad, first learn to look at the nameplate on the power supply, we don't need to understand all the content on the nameplate, just understand what the voltage of the various colors of the line is. We can make simple measurements by following the identification on the nameplate: Red +5v Yellow +12v Orange + White -5v Blue -12v Purple +5V. See if you can see if you can see if you have the correct values for the above labels.
4. Measure red +5V, the measured value is not much different from the nameplate marker, and the red line can be excluded!
5. Measure yellow +12V, the measured value is not much different from the nameplate mark, and the yellow line can be excluded!
6. Measure orange +, the measured value is not much different from the nameplate marker, and the orange line can be excluded!
7. Measure white -5V, the measured value is not much different from the nameplate marked value, and the white line can be excluded!
8. Measure blue-12V, the measured value is not much different from the nameplate marker, and the blue line can be excluded!
Purple +5v.
9. Measure purple +5V, the measured value is not much different from the nameplate marker, and the purple line can be excluded!
10. Until the measurement of various color lines is completed, if the measured value is not much different from the nameplate value (within the range of plus or minus 1V). It can be said that there is no fault in this power supply, otherwise it can be accurately judged to be a power failure.
Note: When using a multimeter to measure, be sure to adjust to the DC voltage level.
The damage of the power supply of the computer host will also cause the computer screen to appear blurry screen or system instability and other failures, if the computer encounters these faults in operation, then it is necessary to conduct a comprehensive test of the power supply.

Buy a new one, I personally like Huntkey, the largest power supply manufacturer in China. >>>More
You can first determine whether the power supply is really broken First unplug the end of the power supply connected to the motherboard, use a binding wire or needle-nose pliers (conductor is OK), one end is plugged into the green wire hole connected to the power supply and the motherboard, and the other end is plugged into any color hole, and the power supply is connected If the power supply fan turns, it means that the power supply is not broken, if it does not turn, the power supply is broken >>>More
The purpose of several sets of output voltages of ATX power supply + is provided to the motherboard, CPU, memory, various boards, etc.
I can tell you with certainty that it can't be a problem with the power supply at all. Because the input voltage of the computer is allowed to be between 190-230 volts, that is to say, the voltage will not affect the normal operation of the computer. >>>More
