The computer can start, but it can t enter the system, whether it has nothing to do with the hardwar

You say "can't enter the system" and can't judge that the specific fault is in**.

If it stops on the boot screen (or motherboard information) of the motherboard, it is usually a hard disk problem.

If the screen passes through the motherboard, but then the blue screen. It's mostly a memory problem.

If it stops on the operating system splash screen, it may be an operating system or driver issue.

In this case, you can reboot and press F8 to try "Safe Mode", if Safe Mode can't get in either, it may be a serious operating system problem).

If "Welcome" appears, or if the desktop appears but there is no icon. Most likely the problem is caused by the virus.

Most of the problems I've seen like not being able to enter the system are caused by viruses, but many antivirus software runs on the Windows interface, and it can't be killed if you can't enter the system.

The solution to this is to first repair your operating system (reinstall it). After that, you should install an antivirus software with a "pre-boot antivirus" function (such as kv2008), and if this problem occurs again, it can be solved by killing the virus before starting.

Check first to see if the memory and graphics card are loose, and if there is any problem with the hard disk data cable. If not, reinstall the system. It's a hardware problem!

Most likely, there is a problem with the system. It is recommended to reinstall the system.

Try connecting the hard drive to another computer, or change the power supply. Most of the time it is due to the power supply. There is a problem with other hard drives.

If you have the conditions to replace it with good hardware, you can basically find out the problem.

Computer practitioners, to tell you accurately, are the problem of the hard disk, and the hard disk has bad sectors.

Any hardware failure on your computer will cause it to fail to boot.

Specific judgment failure analysis:

The power-on screen is displayed, but it does not enter the system. It may be that the system program is damaged, or the hard disk has a bad sector or other fault, the power-on switch screen has no display, the black screen, and the CPU fan can rotate, which may be a fault of the graphics card, memory, motherboard, etc.

Press the power button when the power is on, the power light is not on, and the computer has no response, so you should consider and detect whether the power supply is normal; and the motherboard is faulty.

Specific problems are troubled step by step, and you can.

Replace a component to accurately determine the fault.

You can solve computer problems!

If the keyboard light is not on, it means that the motherboard is not powered on, and it is better to go to the computer company to test the motherboard.

If the computer can't even be powered on, it can only be sent for repair. Motherboard, power supply, graphics card, memory Mainly these 4 are the most likely to have problems.

There are many reasons why the computer can't start, small horses and carts, hardware problems, software problems, system problems, etc., it can't be said that it must be that hardware problem, it depends on what specific prompts are given!

If you can't start it for a long time, can you start it in the end?,It may be a hard disk problem.,If you can't start it, you may be able to start the system.。 Others are also possible.

It's not a hardware problem, it's a system problem, it said that a registration file in the system is missing, resulting in a boot failure, just reinstall the system!

If it's a blue screen, the hard disk track is broken.

Did you see if the power was plugged in first? Is there electricity?

1 Check whether the antivirus software has killed the virus, you can determine whether it is caused by the computer system poisoning or malware, if there is a virus, it is recommended to use the computer manager to kill the virus, or if it doesn't work, reinstall or restore the system, you can solve it.

2 **Computer Manager hardware testing tool to test the temperature of each hardware of the computer, open the case, see if the CPU fan and graphics card fan rotate normally, find out the problem, and change the CPU fan.

3 If you add a discrete graphics card to the trapped computer, and the power supply is not enough, you can only change to a higher power power supply, and the power supply is unstable for a long time, so you must change the power supply to test.

4 Shut down, touch the motherboard south bridge hall, north bridge chip, graphics card chip, if it is very hot, Wang Zhiyan is likely to be broken, to be repaired.

It's already to this interface.,It's generally a system problem.,Let's start from scratch.。

System problems, reinstall the system, look.
