First, the memory module is damaged
Computer often crash, blue screen or can not start normally, after boot can not enter the operating system, in general, we through the replacement elimination method to find the fault, and most of these failures are caused by motherboard, graphics card and other hardware equipment damage, of course, due to improper software settings or the system encountered virus invasion may also cause the above failures. Locating faults is often a headache, but in general, memory failures are often the biggest cause of such problems, including memory corruption, incompatibility, or memory slot damage. That is to say, it is best to eliminate the cause of the memory before judging whether the fault is caused by other components, after all, this is the greatest possibility. This article will introduce in detail several manifestations of memory failures, troubleshooting methods and the essential causes of memory failures.
Second, the motherboard components are damaged
1. Component reasons: The quality of the chip and other components on the motherboard is not good, resulting in aging and damage to the motherboard, resulting in the failure of the motherboard.
2. Human reasons: When using the computer, hot-swap hardware or use metal objects to touch various connectors at will, resulting in the failure of the motherboard.
3. Dust and static electricity: due to dust or static electricity, the motherboard is in poor contact, short circuit or burns the chip on the motherboard, resulting in the failure of the motherboard.
4. Lightning affects power surges sometimes invade through the network cable interface during thunderstorms, should avoid using in thunder, or purchase lightning protection motherboards.
5. Static electricity Avoid touching the motherboard with your hands, and discharge it first when installing, and static electricity can be released by touching the water pipe. Causes of poor contact: Due to rust, oxidation, weakening of elasticity, pin desoldering, breakage, etc., various chips, sockets, and interfaces in the motherboard are in poor contact, resulting in the failure of the motherboard. According to the characteristics of the motherboard and the cause of the failure, when the motherboard finds a fault, the motherboard fault diagnosis method is as follows.
Third, the hard disk is damaged
There are two situations in which a computer hard disk is broken, one is a logical failure and the other is a physical failure. Logical failures are more common, such as hard disk partitions not opening, accidental deletion of files, etc., which can be repaired by some repair software. For physical failures, you need to try to open the disk to recover the data. It should be noted that the hard disk is a delicate device, very fragile, before repairing should wash the hands first, release the residual static electricity of the human body before operation. If the hard disk is damaged and data is lost, it can generally be recovered, but the recovery method depends on the damage of the hard disk.
