What should I do if the computer starts up slowly, automatically shuts down, and the computer turns

This may be a hardware problem, specifically it may be CPU memory, graphics card, motherboard, etc., because you say that the screen is going to be black for a minute, this is not normal, the computer's boot sequence is first CPU, then memory, and then graphics card, these are fine, the display will be displayed, and then it will be booted according to the boot order of the BIOS, you are the analyst, right, what is the specific problem, you can only take it to the place where the computer is repaired.

Check to see if your driver is updated.

According to my estimate, it's a hard drive problem, find a hard drive to replace it

I wonder if you opened the case and saw it? Suggestions: 1. Ash cleaning; 2. Check whether the power supply, CPU, and discrete graphics card fan have poor heat dissipation; 3. Whether there are bad areas in the hard disk; 4. Run five or six laps before entering the system, and I usually have a maximum of 2 laps after installing the system.

The operating system should be installed according to the hardware configuration; 5. If the above problems are still like this after they are solved, they can be solved by flashing the BIOS.

If the above points are dealt with, there should be no more problems with the computer. I have experienced a lot of computer problems in this regard, new computers, old computers, so I think it is nothing more than these points.

1. Most of the hard disk has bad sectors or the relocation time is too large, scan the disk with MHDD to see, and replace the hard disk if it doesn't work.

2. Check the heat dissipation, the most important thing is to see if there is any ash between the CPU fan and the radiator.

3. Boiss setting problem.

The situation where the computer turns on and off very slowly wastes a lot of our precious time, so what? Let's follow me to learn how to solve the problem of slow computer startup and shutdown.

The computer starts and shuts down very slowly, and the solution is 1

First: there are too many programs to start at computer boot, and after installing the software, do not check the auto-boot items, which will cause the program to start automatically at boot and cause slow boot speed;

Solution: Pay attention to the selected items after installation when installing the software, and be sure to check off the boot startup item, because the general program will be booted by default, if you don't pay attention to the selection, then we can use the tool to close the boot startup item that you don't need.

Second: shutdown is not a normal exit, after the computer is used, directly press the shutdown button to shut down, and some even press and hold the main shutdown button to force shutdown, which may be very fast. But it will bring you a very slow progress in the next boot, and it will also have a great impact on the service life of the computer;

Solution: Don't panic every time you use the computer, close all the programs in use normally and then shut down the operation, if you can't close it, you can use the program manager to close.

Third: the computer is used for too long, the computer has a lifespan, the general life is two to three years, and it will turn on and off very slowly when it is used, which is a normal phenomenon.

Solution: Replace the computer system or reconfigure the computer.

The computer turns on and off very slowly, and the solution is two

First you need to turn off the update, having experience, which is one of the most time-consuming things.

Don't install some unnecessary software, now the security of Windows has been done very well, as long as you don't browse some unhealthy **, it will definitely not be poisoned, and there will be no Trojans.

Use Ctrl+R to start execution and enter the command.

Set the number of CPUs to the number of CPUs of your computer, 2 if it is dual-core, 4 if it is 4-core, the memory is the configuration of your computer, turn off the boot screen, etc.

5. Click the "Startup" tab to delete some non-system startup items.

6. The last and best way is to choose "hibernation" when turning on and off, so that the computer can store all the current working states and restore them when they are turned on again. And it can ensure that the power on and off are fast.

The CPU temperature is too high.

Replace the high-power fan.

Keep the room well ventilated.

The power supply voltage is unstable.

Buy a voltage regulator or UPS power supply.

Too many programs are open.

Memory is heavily occupied.

Close unnecessary programs under msconfig.

Low CPU or memory configuration.

Replace the CPU to add memory).

There are logical or physical bad sectors in the hard drive.

Find a professional to overhaul or replace).

There are viruses. Let's kill it.

Too many junk files.

Too many fragmented files.

There are compatibility issues with hardware and software.

The BIOS settings are incorrect.

Reset the BIOS

Dust and dampness are to blame.

Clean the chassis and keep the inside dry and clean.

Run msconfig, remove all checks from the boot bar, and leave only ctfmon, and that's it.

First check the hardware such as the hard disk, then the software such as the system...

There is a virus to try in Rising Antivirus.

or redo the system.

The system files are broken, so let's reinstall the system.

System rework. Slow boot is because there are too many boot startup items. Turning on and shutting down is a software conflict in the system.

Because your computer is not booted normally, it will be detected every time it is turned on. Turn on your computer. Press F8 to enter that mode (keep pressing until you go in).

There's an option in there. (the last correct configuration) can be tried or not. If it doesn't work yet.

One-click restore. Or reinstall the system.

Advanced coms look at the CPU temperature and fan speed If it is normal, it is a virus.

There are many reasons why a computer boots up slowly.

My experience is this:

1. There are too many startup items, solve: turn on the computer, start - run - enter msconfig - close the unwanted startup items (only keep the input method and antivirus software);

2. The computer has been used for a long time (solution: regularly clean up the computer dust, generally once a year, use the ordinary once a year, if you don't clean it well, send it to the computer company to clean up about 30 oceans);

3. There are too many viruses or garbage in the computer. Solution: The computer should be equipped with antivirus software and software assistant similar to 360; Regularly check for viruses and clean up system garbage, etc.;

4. Try to put as few files as possible on the desktop, which has a great impact on the startup;

5. If two anti-virus software are installed, only one anti-virus software can be installed on one computer.

6. If the system file is wrong, use the partition check and sorting tool that comes with the system to check and sort. Go to the Start Menu >> >> >> >> >> >> >> >> >> >> >> >> >> >> >> >> >> >> >> >> >>

D disk), hard disk fragmentation with the system comes with the line, for bad sectors, you can use the hard disk bad sector test repair software test to determine the existence of repair, repair.

7. Turn off the system updates that come with the system.

If none of these can be solved, your boot time is still very long, and there may be some hardware problems.

It is recommended to find a professional or computer after-sales service to solve the problem.

The computer finds the reason to be honest, not an experienced person, it is not easy to solve it on the network, you can take a look at the advanced security mode, and do not redo the system, this is the easiest solution.
