What should I do if the black screen of the computer can t be opened, and the optical drive can t be

The CPU fan is rotating and stopping, and it is very likely that the problem is the fan.

CPU fan may be difficult to rotate due to dust and other factors, the fan has no speed, which means that the CPU can not dissipate heat, we know, modern CPU has self-protection burn-out function, the temperature exceeds the limit temperature, it will automatically shut down (instant shutdown, even the power supply is turned off), when you just turn on, the temperature is zero, after a few seconds, the temperature begins to rise rapidly, if there is no CPU fan to dissipate excess heat, the CPU self-protection function will automatically cut off the power supply, so the computer will not be able to turn on.

If that's not the case for you, (and the power is cut off after a while), it's a problem with the power supply or motherboard. But it should be unlikely.

As for the optical drive not being able to pop, it must not have been installed.

The optical drive can poke that small hole with a paper clip, i.e. open it physically by a physical method. Add a primary hard drive to boot up, and then use Kaspersky to disinfect your hard drive. Plugging in is generally a storage device failure, and most of them are memory failures.

It is recommended to unplug the memory and reinsert it, and if it doesn't work, try to change the memory.

There are also some black screen phenomena that the computer will not alarm, and the easiest thing is to analyze the specific problem according to the mathematical "exclusionary method". Check whether there is a problem with the power terminal board, remove the relevant supporting parts of the computer, and replace it with some other equipment that can be used to check whether the power terminal board is working properly. If there is no fault in the power supply connection board, then check whether the connection between the computer power supply and the motherboard is normal according to the normal procedure of the wheel, that is, check whether the power supply of the motherboard is normal.

If the socket is not connected incorrectly, you should check whether the power supply is burned, and if the power supply is burned, the power supply fan will also stop. If you suspect that this kind of problem is the case, please unplug all the power cables of hard disks, optical drives, and floppy drives, and then restart the computer, and see if this situation is solved after the power consumption rate is greatly reduced. If the problem persists, rule out whether the motherboard BIOS has been accidentally damaged by a virus such as CIH, or if the motherboard has a bad contact or short circuit in the sonotrod.

Hello dear, happy to answer for you.

Slide the optical drive to another computer to try, if it can be turned on, it means that there is no problem with the optical drive, check whether the power cable in your own computer is faulty, and try to change the power cable. If you have unplugged and unplugged the optical drive when the computer is turned on, it is very likely that the optical drive is burned, which will lead to the above problems.

Hope mine is helpful to you!
