Frequent computer restarts and freezes!! 5

Frequent computer crashes are generally caused by a few points, 1Viruses, not much to say about this, because some viruses will occupy hardware resources crazy at high temperatures, mostly because the heat sink is too dusty, and the fan speed is reduced to cause the CPU to be high, of course, the drying up of thermal conductive silicone can also lead to this situation 3Hard disk bad sector,When you operate the software,The moment the hard disk scans to the bad sector,It's the time of the crash,This is not said,Change to solve,Of course, there is also software that shields bad sectors,But I don't approve of using this method Always have to lose data,Or yourself are unlucky4.

The south bridge or north bridge chip is overheated, touch it with your hands to see if it is particularly hot, if it is very hot, go to the computer repair office to install a small radiator Basically, the above four points, you check it yourself and then deal with it.

Fix the CPU cooling problem first, and then reinstall the system.

It should be an automatic shutdown caused by high temperature caused by poor CPU heat dissipation, which is manifested in the operation of high CPU occupancy such as playing games and watching movies, and the computer will automatically power off without any warning for about 10 20 minutes. Even when the system is reinstalled, it will be automatically turned off.

Rebooting often also shuts down automatically, and you need to wait a while to turn it on again before you can enter the system normally.

Replacing the silicone grease to clean the dust is ineffective, please see method 3:

Workaround:1First of all, turn it off, remove the CPU heatsink, remove the fan on the heatsink, clean up the dust, dial the fan blades to see if it rotates smoothly, if it is difficult to rotate, uncover the label on the back of the fan to see the bearing, add a small amount of lubricating oil dropwise and then paste it.

2.Go to the computer repair area and ask for some silicone grease (something that is white and thick, like toothpaste). Wipe the old silicone grease on the heat sink and CPU with a paper towel, apply the new silicone grease evenly, do not apply too thick, and reinstall the heat sink and fan.

Problems can usually be solved.

If you don't have the ability to do it yourself, you can directly take the machine to the place where the computer is repaired, let him use a blow gun to blow the dust inside the case for you, and then ask him to help you change the silicone grease.

3.If the problem is alleviated after replacing the silicone grease and removing the dust, but occasionally there will be an automatic shutdown. Then you are experiencing the same problem as me: the CPU heatsink is too tight or too loose, or the force is uneven.

If the temperature exceeds 70, then untie the CPU buckle to observe, if the temperature is normal, the heatsink is installed too tightly, resulting in insufficient contact with the CPU. If it is more serious when the buckle is loosened, then the heat sink is too loose.

If it's too tight. Use a screwdriver to loosen the heatsink base screws on the top of the motherboard, and if necessary, use a piece of paper to raise the bottom a little. However, it should be noted that all four screws must be tightened, otherwise it will cause uneven installation of the heat sink. You can also use pliers to adjust the buckle to reduce its bite force.

If it is too loose, it is mostly the relationship of the buckle, and it is enough to adjust the buckle with pliers to make it fastened.

Is the voltage on your side unstable? Unstable voltage can also cause restarts. It is also possible that the power supply you bought is not of good quality and the output power is unstable, which triggers the automatic protection function of the motherboard.

If the voltage is unstable, buy a household appliance regulator.

Voltage instability is the main reason for frequent start-up of the photo, but there is another problem not to ignore the graphics card You had better immediately test the temperature of the next Master Lu The temperature of the graphics card is too high It can also lead to frequent start-up If the temperature is high, turn it off immediately to see if the graphics card fan does not turn or there is no silicone under the graphics card fan It is best to go to the repair shop to take a look

See if you can turn on the computer, if not, then check whether the motherboard capacitor is protruding. If there is, the motherboard capacitor is burned. If not, then reinstall the system.
