Is it a power issue or is it the CPU thanks

If the CPU temperature is too high, the CPU temperature will be too high, and the computer will start up. Anyone who knows this truth knows this. You just dust the CPU fan and oil it. Paint the heat sink and CPU connection evenly in the tube silicone and pull it evenly.

The temperature is too high, and the temperature will drop a lot if you turn on the air conditioner.

Let's get a better fan.

It's really not possible to add a case fan.

The heat dissipation is not good, so change to a fan with a larger function.

There are two lines of thought:

1. Since the cause of the power supply fan has been ruled out, you should see if the fans of the CPU and graphics card are normal, and clean up the dust in time. If everything is cleaned up, the silicone is also on, if the fault is still there, then when your computer automatically restarts, immediately touch the cooler of the CPU and graphics card to see if the temperature is very high? (When judging the fault, the case cover is opened in advance), if the temperature is not high and belongs to the range of about 50 degrees, then it can basically be ruled out as a fault in this regard.

If the temperature of the graphics card is too high, it is generally a crash, and if the CPU temperature is too high, the motherboard will alarm first, and then it may crash and restart. ）

2. You mentioned that the power fan used to be very slow, and it was normal if you cleaned it up. Then I can try to judge that when your power supply fan is very slow, there are already dust and other substances that affect the normal operation of your power supply, thus losing the power supply and causing damage to the power supply, resulting in even if you clean up the dust fan normally, the power supply has been consumed, and it is too late to make up for it. So when you're gaming, the more soldiers there are, the more data the CPU will process, and the more power consumption will be.

Because the power supply has been depleted, it cannot support the power of the CPU in time, and its own "crash" causes it to restart, you can change to a normal power supply to verify it.

I hope that even if I can't solve your computer problem, I think it's like exchanging relevant knowledge with each other.

Put the case in an open area and try it I used to play Warcraft also card.

Look at the fans on the CPU and graphics card, it is estimated that there is too much ash.

It should be that the heat dissipation silicone grease is gone, 3 5 pieces of a big box, which is the white thing on the CPU.

This is clearly a power issue.

1. It can be used without a power supply and only with a battery, which means that the motherboard is good.

2. Take off the battery, and then use the power supply alone can be used normally, indicating that the power supply can bring a laptop.

3. The battery + power supply is not good, indicating that the power supply is too small, and you can only bring a laptop, not a battery to charge.

Emergency use: You can use the power supply to charge the battery without turning on the laptop. When fully charged, turn on your laptop again.

You can turn off the power first, turn on the compartment, dial out the memory, use the eraser to wipe the part of the gold finger (that is, where there is a copper sheet,) back and forth a few times, and then insert it back into the memory slot (or insert it back into the memory slot), it's OK, if you have an independent graphics card, you can also use the same method to deal with the graphics card, and then insert it back into the graphics card slot, and finally install it, and restart the computer.

1. If the connection data cable between the computer host and the LCD screen is taken off or the connection cable is damaged, a black screen will appear, and the detection signal line will be displayed.

2. The memory and the slot of the graphics card and the motherboard are not in good contact, such as in the mobile host, accidentally brought to the graphics card, resulting in poor contact, so as long as the computer is almost open to the host body, use the eraser to align the gold finger of the memory (that is, the part with copper plate) on both sides of the wipe a few times.
