Computers often crash Please explain in practice Don t have a bunch of theories

Personally, I suspect that it is a problem with the power supply.

Question 1 It may be caused by the system entering the power-saving mode, it is recommended to install the motherboard driver, or prohibit the system from entering the power-saving mode to see if the problem can be solved.

Problem 2 There may be an aging power supply or an unstable power supply. Blue screen caused by a sudden change in voltage during system boot. When encountering the problem in the future, pay attention to the sound emitted by the hard disk if it appears"Kada"As soon as it sounds, it is very likely to be a power supply problem, or it is possible that the power interface of the hard disk is not in good contact, so try another interface.

It may be a memory problem, such as poor contact, and the quality of the memory, many crooked memories are easy to cause inexplicable problems. You can check if it's a legitimate brand first and test it on another machine.

It's also possible that the motherboard has compatibility issues, causing conflicts and crashes at some point.

1.It may be that some screensaver that requires high performance is installed (I have experienced this situation in the past).As a result, the computer may temporarily stop responding.

2.It may be a malicious plug-in (or virus), or it may be due to a problem with the hard disk or memory, or the system files are missing, so it is recommended to reinstall the system.

3.It's pretty much the same as the first one. (Maybe your computer is too bad!) )4.Hardware issues!

5.Possibly! (There is a common language.)

Tip: Read more books on computer maintenance.

The biggest suspicion is that the CPU is overheating.

If the computer is very stuck when it is running, and it freezes after the card, it is definitely the CPU overheating.

But you said that the dust was cleaned up very cleanly. The fan is normal again.

Does your CPU have fans?

I've had this issue as well. I see that you remove the memory card and graphics card and other related cards, wipe the gold finger clean, and then plug it in steadily. Because I think it's a problem with the contact.

I don't think there is any other reasonable explanation for the poor contact of a piece of hardware, and it is recommended to dismantle what was dismantled when cleaning up before, and reinstall it carefully and carefully again.

If there is a bad sector on the hard disk or there is a problem with the motherboard, you check it.

First of all, you need to determine whether it is the sound from the **, so as to give you a more accurate judgment.

Find a professional to see if your motherboard or power supply is damaged.

General investigation of hair

1: System. 2: Driver.

3: Video memory. 4: Hardware graphics card.

I don't know the configuration, there is no physical verification. One can only speculate.

If it's serious, you'll have to change the graphics card.
