As soon as the computer host is turned on, there is a regular tick ring, which rings every 5 seconds

1) Reinstall the operating system first, don't 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.

Please note: If you restore the system or reinstall it, when installing drivers, patches, software and other things, be sure not to install the things that affect your accident this time, otherwise it will be restored or reinstalled in vain.

2) In terms of hardware, such as hard disk, memory, graphics card, motherboard, etc., if there is a problem, if it is caused by hardware problems, it is recommended to overhaul it.

Hardware issues, check it out.

1 Short: The system starts normally. This is something we hear every day and it also shows that there is nothing wrong with the machine.

2 Short: General error, please enter CMOS

setup, resetting the incorrect option.

1 long and 1 short: There is an error with the RAM or motherboard. Try to change the memory, if it still doesn't work, you have to change the motherboard.

1 long and 2 short: The display or graphics card is wrong.

1 long and 3 short: The keyboard controller is wrong. Check the motherboard.

1 long and 9 short: motherboard flash

RAM or EPROM error, BIOS corruption. Try a different block of flashram.

Constant ringing (long sound):

The memory module is not plugged in tightly or damaged. If it still doesn't work, you can only replace a memory module.

Ringing: The power supply and monitor are not properly connected to the graphics card. Check all the plugs.

Repeated, short ring: Power issue.

No sound, no display:

Power issues.

There is only one long sound that keeps intervals, which is the memory alarm sound, usually the memory is not plugged in or the gold finger is not well contacted, or the memory is damaged.

The reason is that the computer self-test can't pass, the long sound is that the motherboard has not passed, and the short sound is the memory. There is a little trick that is very useful, you can first unplug the memory, start the computer, if it still rings, it is the motherboard or graphics card, if it does not ring, it is the reason for the memory, if it is the reason for the memory, reinsert or replace one, otherwise, you need to replace the motherboard or graphics card, it is recommended to be operated by professionals.

Are you able to turn on the machine when it rings!?If yes, it's your hard drive! There's something wrong with your hard drive

The laptop won't turn on, and it rings. Most of them are memory module issues. This problem can be solved after disassembly and cleaning.

When the computer is turned on, it will sound 5 times in a row, which is the BIOS alarm sound of the award:

1 Short: The system starts normally. This is something we hear every day and it also shows that there is nothing wrong with the machine.

2 Short: General error, please go to CMOS setup and reset the incorrect option.

1 long and 1 short: There is an error with the RAM or motherboard. Try to change the memory, if it still doesn't work, you have to change the motherboard.

1 long and 2 short: The display or graphics card is wrong.

1 long and 3 short: The keyboard controller is wrong. Check the motherboard.

1 Long 9 Short: Motherboard flash RAM or EPROM error, BIOS corruption. Try a different block of flashram.

Constant ringing (long sound): The memory module is not plugged in tightly or damaged. If it still doesn't work, you can only replace a memory module.

No sound, no display: Power issue.

Why can't I enter the system when the computer is turned on?

1.Hardware changes.

When the hardware configuration of the host has changed, but we are using the POST function, the system can not recognize the newly added hardware at this time, and will work according to the old configuration, at this time, it will be able to power on after booting, but there is no "beep" sound when starting normally, and there is no image display on the display, only the sound of the fan turning.

Another reason is that the newly added hardware is not compatible well, which leads to the above situation.

Settings changed. When the BIOS is set incorrectly, such as the incorrect setting of the read and write parameters of the memory, the incorrect mode setting of the hard disk, and the incorrect setting of the onboard sound card and the integrated sound card, etc., it will cause the normal boot to fail.

3.The hard drive cable is incorrectly connected.

In this case, the data cable of the hard disk is not in good contact, the poor quality of the data cable causes too many errors in the data transmission, the data cable is plugged in incorrectly (the motherboard end is connected to the hard disk end), the master and slave hard disk jumper is wrong, and the hard disk capacity or mode setting is incorrect.

4.The contents of the main boot area of the hard disk are corrupted.

When the contents of the main boot area of the hard disk are rewritten by other programs or destroyed by viruses, or the partition table of the hard disk is cleared or artificially set to a logical lock state, it will crash at this time.

The monitor is not connected properly, plug the cable into place, restart and boot everything is normal.

There is an error in the memory, reinsert the memory module.

When the computer starts up, check the memory first, and then wipe it back and plug it in tightly. If it can't be solved, there is a problem with other hardware, give you the most complete information, and read and judge it carefully according to the specific situation: if you look at these carefully and carefully and do not help you, send them directly for inspection.

Detailed explanation of the motherboard alarm sound.

1. "Didi...""Continuous, short tones are generally common when there is a problem with the power supply of the main unit.

2.The sound of the ambulance "Woo la Woo La" was accompanied by the sound of the starter non-stop.

This situation is the system alarm sound of CPU overheating, mostly because of dusting inside the host, cleaning the CPU cooler or because the CPU fan is replaced with a new one, because the installation is not in place.

3."Tick...."Tick....", a continuous interval of long tones. The sound of memory alarm is generally due to loose memory, poor contact between the gold finger of the memory and the memory slot, oxidation of the gold finger of the memory, and failure of a chip in the memory.

4."Tick...., Didi" is a long and two short continuous chirps.

This is a graphics card alarm, usually the graphics card is loose, the graphics card is damaged, or the power supply part of the graphics card of the motherboard is faulty.

5.There is no movement after two long tones of "beep", and after a while, you will hear the sound of "squeak" reading floppy drive.

If there is an image display, it will indicate that the system will boot from the floppy drive and is reading the floppy disk. If there is no floppy disk in the floppy drive, the system will prompt that no system cannot be started, and the system is suspended.

6.When pressing the three keys "Caps Lock" and "Num Lock" and "Scroll Lock" in the Win system, the PC speaker of the host computer has a "Di" similar key sound.

7.A short "tick" sound, under normal circumstances, this is the prompt sound that the system self-test has passed and the system has started normally.
