How to detect damage to hardware? How to detect if your computer hardware is damaged

Generally, it can be turned on normally. Don't panic too much. The current laptop should still be able to withstand a little beating.

Most of the components in the general computer are fixed on the motherboard, there is no big problem, is there a shell on the outside of the notebook? There should be no direct damage to the interior.

If the landlord insists on testing, it is recommended to use everest to check to see if the parameters are consistent with the nominal parameters of the notebook.

If you really don't feel at ease, you can take it to customer service to test it, the notebook is not a desktop, it is more precise, don't disassemble it yourself.

Don't worry, Dell's book, the quality is not bad. Hehe, good luck

The hard disk is scanned with chkdsk.,But if it's dropped in a shutdown state.,There should be no problems except for the shell.,At most, you can check whether the screen has broken spots or something.。

In addition, everest is useless, just use start-> to run, type chkdsk f, see if there are any bad sectors on the hard disk, and if there is no abnormality, it will be OK!

I have a software that has detected hardware, and the specific name is not clear! But I still have compressed files on my computer! The name aida32 version is pressurized and installed, and then run the computer icon file with the name of aida32!

In Chinese, each hardware performance can be tested! Try it !

Hope it helps!

Accessories other than the hard drive are not necessary to be detected.

1, Master Lu.

2. Fault diagnosis card is the most commonly used cheap (10-30 yuan) hardware to diagnose computer failures.

After the computer is started, it is stuck in that step, and the ** is displayed, knowing that the problem is stuck**, change the corresponding hardware, and repair the computer.

In fact, there still seems to be no software to detect the quality of hardware. Because the software is detected by the program command, it can only judge whether the hardware has this function within a limited range, but its function is realized by the driver, there is no driver or the program is incomplete or damaged, and it cannot operate normally, not necessarily that the hardware is broken, and the software only detects that the function is abnormal, and cannot accurately judge whether the driver is broken or the hardware is broken. In other words, the software detects the existence or absence of some hardware through normal hardware operation, but if there is no hardware or the hardware is broken, the software will not play much role.

Generally speaking, the thing that detects good or bad hardware right now is the detection card. The detection card is hardware, not software. There are also special testing instruments for different hardware, which requires professionals to detect and judge the quality of the hardware.

At present, some detection software, such as Z-CPU or a master, can only detect whether most of the hardware drivers are normal, brand, model, performance, etc., and can hardly detect the quality of the hardware.

Tutorial: How to check if your computer is working properly.

Through Master Lu, the hardware can be effectively detected.

Second, click on Hardware Detection (for a full detection).

Finally, review the detection results.

This technical work requires a certain amount of maintenance knowledge and experience before it can be done.

1. Observe the performance of the computer during startup, roughly judge the problem parts according to the clues on the screen, or the fault performance, and analyze the cause of the failure;

2. Precautions before maintenance operation, first soft and then hard to eliminate the influence of software. For hardware operation, you must first wash your hands, discharge the static electricity on the human body, turn off the power cord, and disassemble the chassis;

3. The simplest, easy-to-implement and most effective detection method is the substitution method. That is, replace the suspected accessories with normal accessories and verify the faulty accessories. If the power supply is replaced, it can be known whether it is a power supply problem, or a problem with the motherboard and its accessories, as well as whether the contact between the plug-ins is unreliable;

4. This method is a common method for first-level board-level maintenance, and is suitable for judging the problem of large boards. For further maintenance, it is necessary to use the debug diagnostic card to assist in monitoring the operating status of the hardware, and get the corresponding clues through the display of the diagnostic card.

5. The follow-up maintenance work of the motherboard and graphics card requires special instruments, tools and corresponding motherboard point map reference. It can be handled according to the actual situation, such as the low-end motherboard is replaced with a new board, and the high-end motherboard is sent for repair.

It can be detected with software such as CPU-Z or Master Lu.

First of all, it doesn't mean that the flashing of the machine will definitely turn on quickly.

Flashing simply restores the system settings to the initial values. However, the initial configuration of the system may not make the computer run optimally due to reasons such as the hardware driver that does not match the hardware, too many default processes, and unnecessary boot programs.

If the boot is slow, you can try to disable some boot software in the task manager, and use various PC managers to optimize the boot process, or reduce the virtual memory capacity of the system.

Hardware generally doesn't go wrong, and if it does, it's a big problem. If the hardware is damaged, the system will run unstable, or the system will be blocked or stuck. In particular, if there is a problem with the core components such as the power supply, motherboard, and CPU, it is impossible for the computer to boot up normally.

An error is reported when the motherboard detects hardware during boot. You can determine whether there are any problems during the operation and use of the computer to eliminate them.

If you can boot the machine, you can say that the card, memory, and power supply are no problem, but it can only be that the hard disk read speed is slow, so the boot is slow.

Smell if there is any mushy smell, and if so, continue to smell until you find the source.

For new computers, generally speaking, the possibility of system hardware failure is not very likely, and the main problem is the system installation.

First of all, reinstall the system, it is recommended to use the original system, do not use the ghost system disk. It is recommended to use the version provided by the hardware official website, and do not use the driver wizard to automatically upgrade and install, so that the system stability and compatibility will be much better.

Also, if you're using an SSD, be sure to turn on AHCI and do 4K alignment, otherwise it will severely affect the boot speed.

First of all, we need to prepare an external monitor, which is the best desktop type. Use an external monitor to connect to the external display interface of the notebook, and this cable is the same cable that the desktop monitor usually connects to the host graphics card interface. If the external monitor is connected to the laptop, start the laptop, and if the external monitor shows that everything is normal, then the laptop motherboard, CPU, hard disk, graphics card, and memory module are all right.

That's the problem with the LCD screen of the notebook.

There are several reasons why the LCD screen of a laptop is broken:

One is the problem of LCD LED screen.

The second is that there is a problem with the graphics card interface or line on the LCD screen connection motherboard. If such a problem arises, it is recommended that you don't have to get it yourself, just find the after-sales or maintenance site for testing, if you can fix it as much as possible, if you can't repair it, replace it with a new display screen. If the external monitor doesn't show anything, the motherboard or graphics card is broken.

Generally speaking, the probability of a hard disk being broken is much smaller, basically it can be said that the graphics card is broken, the graphics card is burned out or the circuit connecting the graphics card to the motherboard is broken, because now the notebook graphics card is soldered on the motherboard, and the graphics card is broken, which means that the motherboard is changed. However, if it is only the place where the welding is in poor contact, it can be re-welded.

It may be that due to the high temperature of the notebook, and the frequent playing of games and the thermal performance of the notebook is not good, the temperature of the graphics card will be too high, and the screen will be blurred. If the graphics card is not burned out, you only need to take a "bath" of the notebook, that is, to remove the dust completely, clean the exhaust system again, apply silicone, and replace the fan.

The motherboard will be tested for hardware after powering on.

The test results are displayed in the form of a buzzer sound.

If there is a problem with the hardware, the buzzer will beep for a long time and will not turn on.

Right-click on My Computer -Properties -Device Manager to see which device has an exclamation mark or is not recognized.
