The computer can t turn on normally, and the trouble is to help 20

The host power light is on, the hard disk light is not on, and the display screen is not displayed?

In my opinion, if there is no drip sound can rule out the problem of the graphics card too!! Then it's your memory module, if the memory module is okay, it's the CPU, the motherboard's problem. You can let the CPU run for a while and then take it apart.

If the CPU is hot, then the CPU should be fine! If the CPU is fine, then it's only a problem with the motherboard!!

And I'm in a situation like yours because of the gray many. It is the reason that there is a lot of gray of the socket of the motherboard! You can give it a try!!

Did you get in there??? If you are enterprising, but you can't get into the system, that's the problem of the hard disk!

If it's black as soon as you enter, it's not shown, that's the problem above.

It should be js that gives you inferior memory.,I don't need to say anything during the warranty period.,I know how to do it.。

If the computer is turned on, it will be restarted without stopping. (That is, the power light is turned on and off, and turned on again when it is off).

First of all, it may be a voltage problem in your home (I have tried this kind of problem, and it is normal when I go to fix it).

It's best to take a look at the store where you installed your computer, and if it works, you ask him to change the power supply for free. (Of course, it can't be ruled out that it's a memory problem, but considering that you just installed the computer, I'm afraid you don't know how to disassemble and disassemble).

Leave it alone, go to the seller first. What should be changed, what should be repaired. However, it can be seen from this that the quality of the computer sold to you is not very good.

There are many reasons why the computer won't turn on, and it depends on the phenomenon.

Whether to power on the first boot, if not, it is a problem with the power supply.

Second, if you power on, see if the display has a display, whether there is an alarm sound, if there is no display, there is no alarm sound, see if the motherboard power supply CPU has a place that cannot be touched, there is an alarm sound, see how many sounds, and the long sound is a memory problem or poor contact.

Third, there is a display, no alarm sound, generally the motherboard CPU contact is not good, you can replug the hardware.

As long as there is a display, there is generally no major problem.

It could also be a problem with the wiring.,My computer just won't turn on.,The graphics card memory is all gone.。。 The last thing to find the cable is the problem.

There is a power supply behind the main unit that is not plugged in.

Solutions to common faults with black screen when computer boots.

There are several possibilities that exist:

1. The memory is not plugged in, or the graphics card is not plugged in, 2. There is a problem with the graphics card, or there is a problem with the connection cable, 3. There is a power supply problem, whether the power supply cannot keep up, 4. The most headache, the motherboard problem, this thing is broken, 5: Check whether the display wiring is connected to the graphics card.

6: The motherboard is broken.

7. There is a problem with the operating system.

8. The pins of the monitor connector.

9. Resolution issues.

Corresponding workaround:

1. Reinstall the memory module and graphics card, be sure to be stable, 2. Replace the graphics card.

3. Buckle the battery on the motherboard, wipe it with a clean eraser, and then install it tightly. If it doesn't work, just change the battery.

4. If the motherboard is broken, there is nothing to do but buy a new motherboard.

6. Reconnect the continuity between the monitor and the graphics card.

7. Find a professional to test the motherboard.

8. Reinstall the system.

9. The pin of the display connector.

10. Resolution problem, software problem is good, as long as it is not hardware, you can find another computer, connect to the display, set a lower resolution, and then take it to test, generally the memory module is loose, just unplug it, wipe it, and then plug it in.

Or if the battery is oxidized, buckle it off and wipe it with a clean eraser.

Then there is the loose wire.

Disconnect the power supply and open the chassis after discharging the static electricity from the body.

Find the position of the JBAT jumper on the motherboard This jumper is generally used to clear the BIOS settings It is often located near the motherboard battery or the four corners will be marked with JBAT The manual will generally indicate that you can't find the description of the same model You can refer to the description of the same chipset of the same brand The following picture shows a jumper plugged in a jbat (currently plugged in 2-3 pins) jumper cap If it is not plugged in, it is three pins.

If you are in the state of three pins and do not have a jumper cap, then congratulations, it is very likely that you have bought a board that has been eliminated from an Internet café Generally, the motherboard will be equipped with a jumper cap at the factory, and it is generally inserted 1-2 pins, so that the BIOS can save the settings normally, if you insert 2-3 BIOS, it will clear the BIOS settings, and it is the same if you don't plug it in.

Now you know what to do, find a jumper cap and insert 1-2, so that your BIOS can be saved normally, from left to right, the needle, connect the first two needles on the left, and it will be right, and it will be marked 1 2

There are generally 2 reasons why your problem arises.

1 In the year 2000, many people had your problem, and it had a name, called the Millennium Bug. The original computer was only set to 1999

And in the year 2000, you'll have this problem, which is usually f1And now the new computer doesn't have this problem. Generally, older motherboards will have this problem.

2 When installing the operating system, change the motherboard settings, or your board.

Resolution. 1 Reply to the motherboard exit setting, press F2 or F4 after powering on, F8 is different from different motherboards. Go to the motherboard settings and change it.

2 Check if your motherboard battery is charged, and if not, replace a coin cell battery.

The motherboard replied that the appearance was set up.

1 Reply to the motherboard exit setting, press F2 or F4 after powering on, F8 is different from different motherboards. Go to the motherboard settings and change it.

Some of your hardware features are degraded, such as the small battery in the console.

If the computer can't turn on, what is the prompt, if it is a blue screen, check the graphics card, and try to unplug and unplug the dust. If it is a black screen, boot repair, or system corruption, the blue screen can also be a system corruption, therefore, it is recommended to reinstall the system to solve it, and the approximate process is as follows:

2. Find the shortcut key for your machine's U disk startup, select it, and press the key more when restarting the computer to enter the PE system of the U disk installation master;

3. After selecting the new machine to enter, select the one-key installation program on the desktop to carry out the one-click installation;

4. If you can't read the image file correctly, try to put the image file into the gho folder;

1- See if the monitor shows English, 'cursor' or 'no signal input', etc.?

2- If the display shows 'no signal input', the main unit is not on.

3- If the display shows 'no signal input', it means that the host has started the graphics card and the signal cable is wrong.

4-The display shows 'no signal input', which means that the host has not started: check the memory module, each plug and other poor contact problems.

Blue screen? Unplug the power and reboot!
