Computers often freeze, monitors and optical drives don t respond

Graphics card I guess it's a matter of the graphics card It's either loose or the fan of the card is broken The optical drive doesn't respond Is the light on when you press it? If it doesn't light up, it's broken, and if your graphics card is integrated, it's a problem with the main version, and 2 problems come out at the same time, and it can also be a problem with the power supply.

Once you are in the system, look at the Task Manager for suspicious processes.

It's very likely that it's a virus, try to use Kaba, nod32, etc., and restore a system if it's convenient to restore the system.

The hard disk light of the host is on, and the monitor is not on, so check the connection interface with the host.

It is possible that the power supply is unstable or the CPU temperature is too high.

Check the power outlets, power switches, etc. The above problem is that the power supply does not start, unplug the optical drive and the useless hardware device connection of the computer first, restore the BIOS settings and start up. No, the power quality is not good, change one.

See if your motherboard has a capacitor drum, if not, there is a problem with the power supply.

Check a few fans for problems.

Chassis power supply fan CPU fan If the graphics card has a fan, there is also a graphics card fan.

Turn on the computer and enter the BIOS to check whether the hardware is normal.

It can only be a problem with the graphics card or memory.

I give two ideas to it. The first is a power failure, the power output frequency is unstable, resulting in the computer not being able to start normally.

The second is the failure of the motherboard, which can be caused by the capacitor around the CPU or the capacitor drum.

If nothing happens to your laptop optical drive, you can choose the following methods to fix it.

1. Turn on my computer, check if there is a disc drive letter, if not, open the chassis to check whether the connection is loose.

2. Start menu, run, enter if it is a w8 system, you need to open all programs and find the run function), open the device manager, check whether the optical drive has an exclamation mark, if there is, you can right-click to delete the optical drive, and then scan the hardware, so that the system will find the optical drive again.

3. Replace several discs for testing, if they can't be read, then the possibility of the optical drive being broken is relatively large, and the optical drive needs to be replaced.

The computer will inexplicably shut down, restart automatically, freeze frequently, and screen frequently. This is the most frequent malfunction of the computer during use. There are three main reasons for this failure:

1. PCI equipment, memory modules and other equipment are not plugged in or loose;

2. The hardware equipment is incompatible or the equipment itself has quality problems;

3. The hard disk has bad sectors or bad sectors. If there is no problem with the hardware, then the reasons for the automatic shutdown of the computer, automatic restart, frequent freezes, and frequent blue screens 95 or more belong to this reason.

The solution to the problem should be "choose soft and then hard", that is:

1. To solve the problem that the hard disk has bad sectors or bad sectors, you can use the sfc command and the chkdsk command to make a soft repair. To do this, click "Start" - "Run" - enter the command character in the window that appears, and then follow the prompts in the window.

It's important to note that sometimes you'll be asked to restart your PC to fix it when you restart.

2. Check whether the PCI equipment (such as graphics card, sound card, network card, etc.) and memory modules are loose, and it is best to replug and unplug them once, and check whether the gold finger part is oxidized or falling off.

It could also be a Trojan virus.

Embed in your computer so that your computer suffers from the blue screen crisis, you can enter safe mode to kill the virus.

With the 360 system first aid kit, it has an excellent effect on all kinds of popular stubborn Trojans, which can effectively remove Trojans and suspicious programs, repair infected system files, inhibit Trojan regeneration, and repair system functions!

This problem is easy to solve, there are two aspects, you can just do it in order:

1. Check the connection line between the optical drive, the motherboard and the power supply: the cause of the fault should be that the system cannot judge after the optical drive is powered on, or the data cable and power cable are not properly plugged in. If you plug in the data cable and power cable of the optical drive again, it should be repaired;

2. If the above situation has been tried invalidly, it is likely to be a problem with the optical drive itself or the line itself, you can change the line to try, if not, you have to change the optical drive.

Set the boot order to hard disk first. In safe mode or with optimization software, the optical drive is disabled from starting automatically. If not, there is only a change of optical drive, which can be caused by a sudden rush between the optical drive and a certain part of the motherboard.

At the same time, press Ctrl AltEnd the task.

Boot and restart, often antivirus! Check if your computer is malfunctioning!

Highly recommend QQ computer butler Kingsoft Poison Bully 2011, very good. Not afraid of viruses.

Poisoned, of course, nothing can be moved.

Hello! It should be that the motherboard and optical drive are not compatible, so it is recommended to try another one.

Is it okay before the repair?

This problem is a self-test hardware problem, there are two possibilities, you rule it out and try it, if it doesn't work, then talk about it.

If you have a problem with the optical drive data cable, try a different one.

The optical drive itself is a problem, unload a friend's replacement and try it.

If it still doesn't work, ask again.

It may be a problem with the optical drive jumper, or it may be that the optical drive is damaged.

I think there are 3 possibilities! The first is that the optical drive has been damaged, when in use, when in contact with the power supply, the internal short circuit, the general computer has automatic protection, so it will automatically power off and shut down. The second one should be that a relatively large voltage is required to start the optical drive, and the capacitor in the power supply is broken, resulting in insufficient power supply and power failure!

Thirdly, it can only be a virus! But I think it's probably the first possibility, you check the optical drive! Go get multiple ROMs and replace them with the current ones!

Diagnose whether it is a problem with the optical drive, the rest is only the power supply problem, it is recommended to replace the power supply, do not replace the whole thing, and the master said that you can change the capacitor, so that you can save at least 100+. Hee-hee.

If an optical drive does not read the disk, we first power on and put in a genuine disc to see if the panel light is flashing, whether there is a "da, da, da" sound, if so, then we can conclude that the sensor between the laser head and the main bearing is broken. Because when we put in a disc, the bald head first needs to be located by the sensor, if the sensor is broken, then the bald head will keep seeking, so that there is a sound of "da, da, da". If the above situation occurs, we only need to open the housing of the optical drive, taking the LG optical drive as an example, there is a thin column with a pencil lead thickness of 3mm in the recessed place next to the main bearing, which should coincide with the front end of the white plastic sheet located in the opposite position of the bald head.

If it is not possible to connect, you can carefully lengthen the tip of the white plastic sheet with glue or other objects, and the problem will be solved.

If the panel light is on and there is no abnormal sound, then open the shell and put it into the disc after powering on, observe the working condition of the leading motor, if the leading motor has no action, you must first check whether the power supply of the leading motor is normal, and whether the transmission belt of the motor is slipping or broken. Whether the status switch is switched freely, because if the switch is not in place, the leading motor cannot be started without a starting signal. To determine whether the optical drive is faulty in the circuit or the laser head is faulty, you can put in a genuine disc of ***, and the following actions should occur:

The laser emitting tube is on (red), and the indicator light on the optical drive panel is on;

The laser head frame has a reset action (back to the vicinity of the spindle motor);

The laser head is retrieved from the inner ring of the disc to the outer ring, and then returns to the vicinity of the spindle motor;

If the laser emitting tube is extinguished and the spindle motor stops after the above actions occur, the optical drive control circuit and servo circuit are normal, and the laser head assembly may be faulty. Otherwise, check whether the optical drive control circuit and servo circuit are normal.

For the laser head, there are generally two light-emitting tubes. If the two light-emitting tubes are normal, the light emitted should be pure red light, also known as full light, which can read ordinary CD disks or *** disks. If the light color is dark and white, it means that there is a light-emitting tube that is bad, then the consequence is not to read *** disk or not to read ordinary CD disk.

If it's a failure of the laser head, you're in for a treat! If the optical drive is old, you can consider replacing it with a new one. Because the laser head is the most precise part of the optical drive, it is also the most expensive part, and it is generally impossible for individuals to repair!

For LG's optical drive control circuit and servo circuit, if the main bearing does not rotate, check whether the data line (on the right) connection between the bearing and the circuit board is intact, and whether the circuit between the connection on the circuit board and the driver chip is unblocked. If the bald head emits a red light during the self-test, but does not seek, then check whether the stepper motor that controls the advance and reverse of the bald head is connected to the circuit board (bottom of the right figure) and whether the circuit between the connection and the driver chip is smooth. Finally, check whether the driver chip is damaged.

If you don't use a ghost device, the ghost system sometimes has this kind of problem.

It may also be that the power supply voltage division is insufficient, try to change to a large power supply.

Recheck that your optical drive ports are all plugged in.

Install the disc driver, restart your computer, and you'll have a reaction.
