The computer can t be shut down, press the shutdown button and that s it, the boot state but the bla

1) Boot repair has something to do with your improper operation before shutting down, right? For example: playing games, watching **, operating big things, and using the computer for a long time caused by the card, right? Or if something unsuitable is installed, the failure will not happen for no reason, right?

Immediately after booting, press f8 to the advanced option to appear in the let go, select "the latest correct configuration" enter to repair, not yet press f8 to enter the safe mode to restore the system or reinstall the system (if the reinstallation is also repaired, it is recommended to overhaul it, if you can enter the safe mode, it means that you have installed something inappropriate, uninstall all the inappropriate things before the accident, or restore the system or reinstall).

First soft and then hard, such problems are caused by software conflicts, inappropriate drivers, and system problems, you can restore the system in safe mode, or not reinstall the operating system, do not install software, patches, drivers, etc., and see if there is still a problem with booting? If you don't install drivers, patches, and software step by step, and find something that isn't suitable, don't install it.

If it is caused by hardware, take out the motherboard battery and put it on the charge, plug and unplug the memory, clean the graphics card, and check whether there is a problem with the hard disk and motherboard parts.

It's really not possible to reinstall the system, if you can't reinstall it yourself, go to the maintenance there to find a maintenance person to help you, it should take a little to spend it, if you can't turn on the machine by any method, this is a sudden shutdown, caused by disk damage, one is to deduct the motherboard battery and put it down, one is to put it for a period of time in the boot to try, or you can't repair it.

Hello, caused a black screen after standby.

The main reasons for not being able to wake up are as follows:

1. If there is no external power supply; It may be that the battery is out of charge, just connect it outside.

Just plug it into the power supply.

2. If you can't wake up when connected to the external power supply; The battery can be removed. Then connect an external power supply to power it on.

3. It is possible that the machine has a hardware failure; There are mainly hardware reasons for this; motherboard and motherboard power failure; Or a faulty display. We basically don't judge the failure of this kind of hardware. It can be sent to a professional for overhaul.

Here's the difference between System Standby and System Hibernation.

1. System standby: temporarily stop operating the computer for a period of time, and the computer will enter a power-saving mode when there is no work to do, but it will immediately enter the working state when performing operations such as tapping the keyboard and moving the mouse.

When the system is in standby, the data that is currently running is stored in memory, and the machine only supplies power to the memory, while components such as hard disks, screens, and CPUs stop supplying power. Since the data is stored in fast memory, it is faster to enter the waiting state and wake up. However, this data is stored in memory, and if the power is cut off, the data will be lost.

2. System hibernation: Computer hibernation is when the computer is not operated for a long time, the computer stops working and turns off the power of most components, at this time, you need to press the wake up button to wake up the computer and enter the working state.

When the system is hibernating, the computer will save the data that is currently running in the hard disk, and the power supply of the whole machine will be completely stopped. Because data is stored on the hard drive, which is much slower than memory, it is relatively slow to go to sleep and wake up, and you can completely disconnect the power of your computer while you are sleeping.

1.The machine is overheating, especially the graphics card or hard drive.

2.Hard disk error or bad sector, causing the system to lock up, 3Virus or Trojan attacks,

First of all, you have to judge whether the host hard disk is still working when the screen is black, if the hard disk light is still flashing, it means that the host is working at least normally, then it may be that there is a problem with the graphics card or display, if the hard disk is not working, the fault should be on the host, the motherboard is more likely to fail, carefully check whether the capacitor on the motherboard is bulging, leakage, or take it to a professional maintenance department to test.

You look at your event viewer and see what programs are in it that are preventing you from being woken up.
