The computer turned on again after a while, what s going on!

Immediately after booting, press f8 to the advanced option to appear in the let go, select "the latest correct configuration" enter to repair, not yet press f8 to enter the safe mode to restore the system or reinstall the system (if the reinstallation is also a restart, it is recommended to overhaul it, if you can enter the safe mode, it means that you have installed something inappropriate, uninstall all the inappropriate things before the accident, or restore the system or reinstall).

First soft and then hard, such problems are caused by software conflicts, inappropriate drivers, and system problems, you can restore the system in safe mode, or not reinstall the operating system, do not install software, patches, drivers, etc., and see if there is still a problem with booting? If you don't install drivers, patches, and software step by step, and find something that isn't suitable, don't install it.

If there is a hardware, take out the motherboard battery and put it on the charge, plug and unplug the memory, clean the graphics card, check whether there is a problem with the hard disk, and if it doesn't work, just overhaul it.

According to what you said, "I have tried this before, and then I changed the power supply and it was fine, and it only took two months" that is estimated to be 80% of the power supply. Is there a warranty for replacing the power supply? Or did you add money?

It is estimated that the boss changed a miscellaneous power supply for you, and the unstable power supply caused the computer to restart. You'd better change a brand at a time, such as Huntkey Calm King, Great Wall, Xingu, these clerks are very good, the miscellaneous power supply is unreliable, and some profiteers give you a broken power supply that they repaired, the quality is not guaranteed at all, you think about it yourself.

You install Master Lu first, pay attention to the temperature of your computer hardware is mainly the temperature of the CPU, there are generally only two reasons for the abnormal restart of the computer, one is the insufficient power supply of the computer, that is, the power supply is insufficient to cause the restart. If the CPU exceeds the temperature value set by the overheat protection in the BIOS (computer basic input and output system), the motherboard will automatically restart to protect the CPU from excessive temperature and thermal damage. Other hardware temperatures that are too high will only cause the Blue Screen of Death instead of restarting.

How can you tell what the cause is? Let's first determine if it is the second possibility, that is, the CPU temperature is too high, first install Master Lu to see the temperature of each hardware, the CPU temperature is above 50 degrees, you should be careful, and look at the speed of the CPU fan below 1,000, even if the speed is too low, the fan speed is too low to cause poor heat dissipation and restart. If the CPU temperature is too high, then open the case to remove the dust and find a hair dryer to cool the air, blow the dust, if it is a fan problem, clean the fan or directly change the fan, if the fan is fine, pay attention to whether the thermal grease between the CPU and the fan heatsink is dry, in short, the temperature of the CPU is no problem when it drops.

If the CPU temperature is normal, then you can only consider the power supply, and pay attention to whether the power socket plug contact is intact and loose? In short, be careful, even if you can't find the problem, the description will make the problem more clear, after all, every computer is different, some problems are strange, only you can solve them carefully, good luck.

Turn on the host to see if there is a lot of dust on the CPU fan, if yes, just sweep the dust away, if your memory is two, take one to see, if not, replace it with your friends, or you can kill and kill the virus, if not, you can reinstall the system to see.

If there's no virus, you look at the temperature, and if it's hot, the computer's self-protection system will start, and it will force a restart, or shut down.

You see if your computer is going to be cleaned up, after a long time, there is more dust on the motherboard, and the heat dissipation is not good.

How long is your computer, will it be a power problem, take it to the computer city to change it and try it.

How big is your memory, take it down and wipe it and try again.

The problem should be on the motherboard, you look at the capacitors on the motherboard, is there a few bulging ones, not flat ones, those bulging ones have been blown out.

There are several possibilities.

1.You can enter safe mode to turn the resolution down.

2.If it's a desktop computer, reinstall the graphics card.

3.If there is a virus in the computer, the computer system can be paralyzed in a few seconds, so it is not possible to deny whether the virus is in the computer.

Have you changed it yourself or overclocked or something, if so, put the motherboard down and restore the BIOS.

5.Unplug the memory module and reinstall it, and reinstall the hard disk cable, I hope you can solve the problem.

Software: Poisoning System Problems, Reinstalling the System or Repairing the System.

Hard disk: Frequent crashes due to unstable voltage and poor heat dissipation. (My computer has encountered such a situation, it is recommended to put some silicone on the CPU to see).

Troubleshoot software issues first, and then check the hardware, I hope it can help you.

1: System problem: Reinstall the system or repair the system.

2: The voltage is unstable.

3: Frequent crashes due to poor heat dissipation.

Voltage instability with a voltage regulator.

1 Power supply problem The voltage is unstable or there is a problem with the power supply - it is recommended that the bureau check the power supply with bad faith.

2 System file corruption When the system files are corrupted, such as the fonts under Win2K and the Win98 Fonts directory, the basic files of the system are corrupted, and the system will be forced to restart when it starts up. - It is recommended to reinstall the system.

3.Virus Destruction A typical example is the "Shockwave" virus that wreaked havoc on computers around the world some time ago, and when it occurs, it will also indicate that the system will automatically start after 60 seconds. In fact, there are quite a few viruses that can automatically restart your computer back in the days of DOS - for some Trojans, it is not easy to remove, it is better to reinstall the operating system.

4 CPU problems When the internal functional circuit of the CPU is damaged, and the second-level cache is damaged, the computer can also start, and even enter the normal desktop for normal operation, but when a special function is carried out, it will restart or crash, such as drawing tables, VCD, playing games, etc. - Solution: Try to mask the L2 cache (L2) or L1 cache (L1) in the CMOS to see if the host can run normally; It's not just a good CPU to replace and exclude.

If the empty source can run normally after shielding, it can still be used improvised, although the speed is slower, but it will save money.

5 Memory Problems If a chip on the memory module is not completely damaged, it is likely to pass the self-test (most of them must have POST set), but it will be restarted unexpectedly due to the function failure caused by high memory heat during operation. Most of the time, when the memory is damaged, the alarm will be turned on, but there will still be faults that do not alarm after the memory is damaged and do not power on. It is best to use the elimination method, which can quickly identify the fault site.

6 Poor heat dissipation or temperature measurement failure CPU heat dissipation, the common problems are that the CPU heatsink fixed clip falls off, there is a foreign object between the CPU heatsink and the CPU contact, and the CPU fan has too much dust accumulation after long-term use, which will lead to poor CPU heat dissipation, and the accumulation temperature is too high and automatically restarts - replace the fan.
