The computer is slow and often freezes occasionally.15

The problem will not be in the CPU fan, you look at the CPU fan rotation situation in the say, maybe you have to change the fan.

Poor heat dissipation] The monitor, power supply, and CPU generate a lot of heat during operation, so it is important to maintain good ventilation, if the monitor overheats, it will cause distortion of color, image and even shorten the life of the monitor. Working too long can also cause the power supply or monitor to dissipate heat poorly, causing the computer to crash. CPU heat dissipation is an important issue related to the stability of computer operation, and it is also the "hardest hit area" where heat dissipation failures occur.

Dust Killer] Too much dust inside the machine can also cause crashes. If the floppy drive head or optical drive laser head is contaminated with too much dust, it will lead to reading and writing errors, and in serious cases, it will cause the computer to crash.

You use 360 to clean up the malicious plug-in to try,Then you reinstall the graphics card driver to try it,The card may be related to the graphics card driver,And use the optimization master to clean up the system garbage to try,Set up the virtual memory,Whether the virtual memory is set up problem,And if you reinstall the system,You only need the system disk C:There are no important files in it.,Reinstall the system is to reinstall the system disk.,It won't be damaged to other disks.,Remember that the system disk C:Don't install any non-system files.。

You can try redoing the system to see if it can be faster, Optimizer is good software, but it's not a panacea.

Redo the system as long as you redo the C disk is OK,I don't think you will install everything on the C disk,After installing the system, don't click on other disk letters,Install a 360 Trojan horse,Then install an antivirus software,Check the virus completely,It should be OK。

Problems with the system.

It's better to start with a fit.

Use 360 to kill the Trojan, clean up malware and system junk, disable some unwanted startup items in the advanced level, which describes the role of startup items, and then upgrade the system vulnerability, and then deorganize the disk, so that the system will be much faster.

Buy another 160g hard drive to transfer important data. The system must be reinstalled. Anti-virus operation is very troublesome.

1. Overheating of the hard disk chip will cause a crash.

The computer screen suddenly goes black during use, and the keyboard light freezes or the blue screen does not respond, and the blue screen prompts hardware failure; You need to turn off the power and wait for a few minutes to return to normal, sometimes it doesn't work, check that all the hardware is not particularly hot, and the temperature is normal; It is also normal for the hard disk to re-partition; If you take the hard drive out of the chassis and place it with the circuit side facing up, it will not crash.

Based on the above phenomenon, it can be determined that the cause of the crash is related to the circuit of the hard disk. As the weather is getting hotter and hotter, the heat generated by the high-speed hard drive is quite large, and if some cooling measures are not taken, there will indeed be some inexplicable crashes.

You can take some effective cooling measures, such as installing a case fan on the chassis to enhance the air circulation inside the chassis, which will reduce the crash phenomenon a lot. However, it is best not to install a hard disk radiator on the hard disk, because although the hard disk radiator sold on the market has a good effect, due to the workmanship, the vibration is quite large. If the hard drive works in vibration conditions for a long time, it will reduce the life of the hard drive.

2. The memory is overheated and causes a crash.

A machine that has been running well suddenly says "memory is unreadable" when it is running, followed by a string of error prompts in English. The same problem often appears, but there is no regularity, sometimes it is used for a day without problems, but sometimes it appears as soon as it is turned on, and it is the most likely to occur when the weather is hot.

When this problem occurs, since the system has already prompted "memory is unreadable", we can start with the memory to find the problem. Now that the weather is hot, the more likely it is that the problem will occur, and it may be due to the unstable operation caused by overheating the memory, which makes the system freeze. For this kind of problem, you can add a case fan to strengthen the air circulation inside the case, and you can also add aluminum or copper heat sinks to the memory to solve it.

3. The CPU overheats and crashes.

CPU overheating can lead to frequent crashes during operation, generally when the CPU performs heavy tasks (such as playing 3D games), the system will suddenly appear a blue screen, at this time can not close the program normally, can only restart. There is generally no obvious pattern to the appearance of blue screens, and most of them occur at critical moments when the CPU load is high, and the main reason is that the CPU is overheating. At this time, you should first check whether the CPU fan is running normally, sometimes the CPU fan is running due to lack of oil. Then observe whether the contact surface between the CPU and the fan is tightly connected, if not, just change to a new fan.

Thank you for my answer! ``

Enter safe mode to see if you are poisoned, if the system can't get in. Hate some. Completely format the hard drive and reinstall the system.
