Computer malfunction. What are the general computer failures?

The scope of your question: Hardware and software.

If you are in a particularly difficult situation; Can reply in a timely manner.

A computer system is composed of a variety of components, peripheral devices and software systems, and various failures will inevitably occur when using it.

Most of the common faults are mainly divided into hardware failures and software failures, in the process of using the computer will encounter a variety of problems, the most common of which are hardware failures, such as not being able to turn on the computer, vase, not finding the hard disk, etc., as well as common software failures, such as file loss, file version mismatch or memory conflict, etc., which will affect the normal operation of the computer.

Common fault 1: no display at startup;

Common fault 2: The Windows registry is often corrupted for no reason, prompting the user to restore it;

Common fault 3: Windows often automatically enters safe mode;

Common fault 4: random crash.

The problem you said, in turn, is a few key points can be referenced, 1, the problem of the computer host ringing, must be the problem of fan rotation, generally most of the days have been long, accumulated too much dust and grease in the air, generally cleaned up will be much better, not good to clean or aging serious need to be replaced (they are originally consumable materials in the computer); 2. The second question, first of all, the biggest consideration is to replace the graphics card, generally there is a problem with the video memory in the graphics card, if there is a spare graphics card, you will know! If the graphics card is integrated with the motherboard, it is easier to do it, just insert the new graphics card directly into the corresponding slot of the motherboard (most of them are PCI-E now); 3. If the problem persists after replacing the graphics card, it may be a problem with the connection between the memory and the motherboard, which leads to a very rare display problem, and generally will not have it!

Could it be that it is unplugged and plugged in to cause hardware damage?

The monitor's cable isn't right, or the graphics card isn't plugged in.

At worst, the graphics card is broken.

What motherboard is your machine using? What chipset, such as Intel's, update his motherboard driver! AMD will update his driver! The problem is solved!

The computer is often stuck on the motherboard model screen, indicating that the system cannot be tested! Graphics card--- motherboard--- CPU--- memory--- hard disk. As soon as the screen appears, you can press the tab button to see where it stops.

According to what you said about the hard disk cable that can be started, it may be that the connection between the hard disk and the motherboard is not very good. In addition to the cable change test, you can also try to plug in the hard disk.

Also, if you have SATA and IDE sockets on your motherboard, you can get an adapter and try it. It should solve the problem.

Upstairs. Computers can't get in. Also use 360 antivirus. What about the layman.

In this case, it is possible that there is a problem with the hard drive, or there is a problem with the installed system. It is recommended to reinstall the system. Or check the hard drive for bad sectors.

The boot check failed, according to the situation, please check whether the hard disk is connected correctly, it is likely that the contact is not good.

Go to BOIS and see if you want to set the boot mode from a USB stick or a hard drive.

The system did not find a suitable boot drive.

Solution: 1. Check whether the computer is inserted into a USB flash drive, mobile hard disk, card reader and other non-bootable devices.

2. Check whether the hard disk connection is normal and check whether the hard disk is damaged.

Generally these are the two reasons.

The boot file of the boot partition is lost, one is that the system is broken, and the other is that the hard disk is not found.

The desktop boot is too slow, restore the system, or clean up the desktop files and boot images, but it doesn't have much effect.

Use an antivirus software such as 360 to clean up the junk and optimize the startup items. If the system is used for a few months or even a year. Let's reload. This one is more thorough.

Hard disk problem, can't enter the system. or memory issues.

Use 360 to fix your IE homepage first, and if that doesn't work, use a 360 first aid kit. The reason why there is an icon on boot is because some software comes with a plug-in. All of them can be repaired with a 360 first aid kit.

It's good to use 360 Security Guard, and you're just playing. If there is any serious problem in the future, it is absolutely okay to use a 360 first aid kit. If you don't understand, you can hi me.

If there are malicious plug-ins and Trojans on the computer, use 360's antivirus software and security guards to kill them.

Didn't you have a 360 installed? The icon is obviously poisoned, try an antivirus with a 360 full scan, and if it's still there, you can choose between buying a good antivirus and system restore.

With 360 Security Guard, you can easily do it!

Well, please kill and kill the virus first, and the computer will do the same if there is a Trojan horse.
