After turning on, the computer s optical drive flashes and sometimes turns on again

Drip drip, drip drip, if you think about it slowly, it is made by poor memory contact, if it is fast, it is poor contact of the graphics card, and it can be solved by wiping the "gold finger" with elephant skin.

The optical drive is loud and can't pop out, and 95% of the belt driven by the optical drive motor is loose or broken.

After booting, there is a blue detection, which is the disk repair tool that the system detects an error shutdown and opens, if there is an illegal shutdown, and it often appears, it may be a bad sector of the hard disk, it is best to choose to back up the important files and then carry out a bad sector detection of the broken disk.

It is recommended to reinstall the system to see.

1.After the start-up, there is a continuous alarm sound of Dididi, which is generally due to the looseness or damage of the memory module, you can pull out the memory and wipe it on its gold finger with new yuan, and then install it.

2.After entering the system, the blue screen, the system self-test is generally caused by a sudden power failure or pressing the shutdown and restart button on the chassis during use.

3.The failure of the optical drive to eject is generally due to internal mechanical failure or foreign body stuck, after disassembling it, check whether the bin box gear is damaged, and whether the internal mechanical parts are well connected.

Go to BIOS and turn the optical drive down to start first.

It's not easy to make that the problem of the system from the bottom of the system.

If it doesn't work, the best way to go to the after-sales service is to let him get it, which is basically a hardware problem.

That's all there is to it.

However, it's best to go to after-sales after all, he can also give you free hardware testing.

How good it is, if it is broken before the warranty period, it can be replaced for free!

There are still questions to be discussed.

It may be that the disc is broken or stolen, take the disc out and wipe it with a soft object, and try again.

Check whether the optical drive cable is normal first! Check if the optical drive is good! Finally, check if the disc can be read on other computers! Or whether the disc is good or bad!

If you are sure that it is not the problem with the disk, you can try cleaning the optical drive head or turning the optical drive head out to read the disk again

If you can rule out the quality problem of the disc, your optical drive head is dirty after long-term use, you can clean it.

Try to change the disc, if it doesn't work, the optical drive is broken!

There is a problem with the power supply, or you can change it to someone else's optical drive and try to see if it can turn on.

If you can't. That's the power issue. If you change someone else's optical drive and it can boot, then it is your optical drive problem.

The optical drive rings because the boot optical drive you set in the BIOS is activated.

The hardware or software is faulty, and the graphics card is not compatible with the motherboard.

Fault performance: First, the graphics card manufacturing process is not standardized, resulting in a short circuit after inserting the AGP slot, which is manifested as no power.

The second is that the graphics card sometimes works normally and can light up the display; Sometimes, the monitor doesn't light up irregularly. However, it is perfectly fine to plug the graphics card into another motherboard. In this case, only the graphics card can be replaced.

The third is that the computer host is also working normally, and the image display of the display is also normal, but there will be occasional irregular image blurs.

Fourth, as long as you use this graphics card, the system will work unstable, either crashing frequently, or often dropping the graphics card driver. In this case, it is also possible that the driver design of the graphics card is defective, which causes the graphics card to work unstable, resulting in a system crash.

You see if there is, and if the driver is uninstalled, it may be.

Try changing the monitor to see if it's the monitor or the graphics card. If the monitor is replaced, well, then it is the original display and should be repaired.

If you change one and it still doesn't respond, then it may be a matter of the graphics card. You can re-plug it to see if there is any oxidation and debris, and then wipe it with an eraser.

Then place the memory module and take a look. In addition, if the CPU heat dissipation is not good, it will also cause the point to not light up.

It really doesn't work, unplug the CMOS battery, ten seconds later, press it again, if it really doesn't work, then go to the specialty shop to see, beware of profiteers.

Is there a disc in the drive? Is it set to start with a heavy optical drive? If it is the above 2 cases, press the DEL button or F1 or F12 (different brands of motherboards) to enter the BIOS settings and find the advanced after booting

BIOSFeatures press Enter to AdvancedBIOS

Features (Advanced BIOS Parameter Settings) interface. Find FirstBoot

device

Use the PGUP or PGDN keys to change CDROM (Optical Drive Boot) to HDD-O (Hard Disk Boot), press ESC, press F10, press Y, press Enter, Save and Exit.

This should be divided into two parts, one is the CD, and the other is the CD-ROM drive.

If the quality of the data reflective surface on the disc is not good, it can cause difficulty in reading the data, forming the fault phenomenon you described, and the solution is to try it on a *** disc.

If you have dust inside the optical drive, aging of the laser head, poor contact of the data cable (experience shows that this possibility is relatively small), and the poor operation of the laser head trolley, etc., can cause the fault you described.

You can solve these problems yourself.

For dust, you can open the case of the optical drive, wipe the laser head with suede and make a circle from the inside to the outside (preferably with an ear blowing ball) to clean it.

For the aging of the laser head, in addition to replacing, you can extend its service life by increasing the current of the laser head, this adjustable resistance is on the laser head trolley, you can try to adjust it, be careful not to adjust it too much, if there is no effect, it must be reset.

For cable problems, you can just reseat it and try it again.

If the laser trolley does not move, you can gently move it with your hand to help it move to see if it can read the data, if it can be read, you can use some white butter to rub some on its track until it can move smoothly.

This situation generally occurs in the following situations:

1. If the computer optical drive driver is damaged or conflicts with the system, it is recommended to uninstall the optical drive and reinstall the driver to give it a try.

2. If the internal files of the optical drive are damaged or missing, it is recommended to rewrite the following optical drive files;

3. If none of the above can be solved, it is generally the optical drive that has been damaged, or a new one, and the current optical drive is also very cheap.

Find a screwdriver yourself, take it apart, it's not expensive anyway, use a piece of absorbent cotton to gently wipe your head to ensure that you don't have a problem using it for another half a year. Remember, move lightly and not forcefully.

Possible causes and solutions.

1.Whether the power supply is too low. Wait until the voltage is normal, and then try again.

2.It's a problem with the motherboard. You can unplug the motherboard and install it again.

Poor heat dissipation. 4.There is too much dust inside the main unit, blow it with a steam cylinder.

My computer is the same, first of all, please check if the CPU fan is working properly, due to the high temperature CPU takes automatic protection. It's just a non-stop automatic restart. Unplug the power supply and wait a while, the CPU temperature is low and there will be no problem when you turn it on.

There is a problem with one power supply.

The second is that there is a problem with the motherboard

1. Consider that the power supply is insufficient, 2. The CPU heat dissipation is not good

The power supply is insufficient, and the belt does not move.

The optical drive flashes because of the detection of optical drives, according to your description, the memory is the culprit, it is recommended: unplug the memory and reinsert it, try to change the memory socket.

Remove the disc from the optical drive and try it.

Your questions are answered separately:

1 The host is turned on, because the host wants to load the relevant connected hardware devices, so as to read the relevant information in the BIOS, so the optical drive light will flash, which is normal, if there is no flashing, it is abnormal, 2 The host light turns on after it goes out, and the power is turned on and off repeatedly. You can try to reinstall the hardware device, by the way, clean up the dust, 3 Have you started the operating system normally in the near future, you try to remove the hard disk, do not connect the hard disk, start for a while, the display screen will say that the relevant system cannot be found, and then shut down, CMOS discharge, .,Then plug in the hard disk and set it up in the BIOS to boot from the hard disk.

4 It is possible that the motherboard is broken, although the probability of the motherboard being broken is small, but it is also possible.

If you have any doubts, send me a message.

Causes of black screen caused by computer host failure: You can analyze the following aspects to find the cause of the failure and take corresponding countermeasures.

1.The power supply is causing a failure. - The power supply is damaged, the quality is not good (miscellaneous), the load is overloaded (e.g. new hardware is added, the power of the graphics card is too small), Replace high-power high-quality brand power supplies (Huntkey, Great Wall, Big Buffalo, Kangshu).

2.Motherboard (CMOS parameters of the motherboard) - Memory, graphics card and other accessories are of poor quality or damaged, and are replaced by the replacement method.

3.The quality of the connection between the accessories,—— the poor contact between the power cord and the socket, the incorrect, loose, and poor contact between the memory, graphics card, etc. and the motherboard. The connection between the graphics card and the monitor, the power socket is broken, and the data cable of the hard disk and optical drive is reversed.

Memory, overclocking issues. - Transitional overclocking, overclocking hardware that is not suitable for overclocking, damaging hardware, and restoring BIOS factory settings.

5.Poor heat dissipation - overclocking, bad fan, poor quality, high temperature system self-protection crash.

You try a new system.

Where else can you boot up when you reboot? If nothing happens, it's the motherboard burned.

In 15 minutes, it is possible that the cooling fan does not rotate, or the CPU temperature is too high and the temperature is too high and it crashes. Sweep the dust. Take a look at the fan.

If it should be eliminated, it will not be a long-term thing! I'm almost twenty years old with such an accessory

The CPU is overheating, the graphics card is overheating, basically these two problems may be that the fan is broken.

This type of fault is a bootable but unbootable fault, and the reasons for this type of fault are as follows:

1) There may be a problem with the contact of the monitor signal cable.

2) There may be compatibility issues with the memory and motherboard.

3) There may be a problem with poor contact in the memory.

4) There may be a quality issue with the memory.

5) There may be compatibility issues with the graphics card and the motherboard.

6) The graphics card may have poor contact issues.

7) There may be a quality issue with the graphics card.

8) The CPU may be corrupted.

9) The CPU may not be installed properly.

10) There may be a problem with the reset hot-start key cable.

11) Dust may cause poor contact problems such as memory and graphics card.

12) There may be a short circuit between the motherboard and the chassis.

13) There may be quality issues with the motherboard.

Follow the steps step by step to check it and it's OK

For example, reinstall the memory, and then boot the test, the fault is still the same, it seems that it is not an installation problem Then check the motherboard slot, and find that there is a lot of dust in the motherboard. Use a small brush and a balloon to clean the dust in the memory slot, then insert the memory several times, and then use the eraser to clean the gold finger of the memory, and then boot the test, and the boot screen appears
