This is the alarm sound of the memory, unplug the memory and wipe it with an eraser, then clean the card slot, and then install it back to try. If it doesn't work, yes.

Memory sticks. It's scrapped, just replace one.

1 Short: The system starts normally and there is no problem with the machine.

2 Short: Regular error. Please go to BIOS Setup and reset the incorrect options.

1 long and 1 short: RAM or motherboard is wrong.

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.

Constant ringing (long sound): The memory module is not plugged in tightly or is damaged.

Non-stop ringing: The power supply, the monitor is not properly connected to the graphics card. Check all the plugs.

No sound and no display: There is a problem with the power supply.

After turning on the machine, it will sound a long and three short ringing.

Analysis: A long and three short rings indicate that the system did not find the graphics card (BIOS), which may be due to the fact that you have not properly ported the BIOS of the graphics card to the motherboard BIOS, or you have not properly flashed the synthetic BIOS to the motherboard, or it may be that your motherboard BIOS format is special (such as ASUS's P2B series) and does not support this method well.

Solution: To solve this kind of problem, the first thing is to determine which of the above problems you have, so please use CBROM to check whether your BIOS is successfully synthesized (see step 5 in the article "Qiao"), if the synthesis is successful, use AWDFLASH (Award's BIOS refresh tool) input under pure DOS, AWDFLASH PN SY, to extract the BIOS file of the motherboard you are using, Then use CBROM to check if the BIOS you're using is the one you synthesized. If the above two steps are normal, then most likely your motherboard does not support it, in this case, you have to arrange and combine the motherboard BIOS and graphics card BIOS of different versions at different times a few times, if it still doesn't work, you have to insert the original graphics card BIOS back (here to emphasize a point, BIOS must not be plugged in backwards, please note that BIOS has a small semicircular notch on one side, this notch should be aligned with the semicircular notch on the BIOS slot.

Remove the graphics card and memory and wipe it.

See if the memory is loose or plug the gold finger of the memory with an eraser.

Buckle the CMOS battery and try reinstalling it.

You're talking too generally, and I don't know what's going on.

The devil knows what kind of indicator light you are talking about red and green.

But generally speaking, the red light is the hard disk light, and the green light is the power light.

If the red light is not on, it means that there is a problem with the hard drive cable.

The computer start-up sound keeps ringing, the fan turns, but the monitor has no image, and the solution is as follows:

1.The fan turns to indicate that the power supply has started to power supply, 2If there is no image on the monitor, and the computer cannot enter the normal working state, it means that the computer has not passed the system self-test, and the motherboard BIOS settings have not been output to the monitorThe fault should be on the motherboard, graphics card, and memory. But sometimes a poor quality power supply and a damaged display can also cause this failure.

4.You can use the operation of cleaning the gold finger of the memory module and the operation of CMOS discharge to solve the problem!

1: You unplug the memory module, don't put it in, and boot it directly. If the computer ticks and ticks, it loses quickly. Erase the golden part of the memory module with an eraser, and then put it back in. If not, try a few more times.

2: If the computer doesn't ring, it's very troublesome, either the motherboard is wrong or the buzzer. Both of them are very troublesome. You can also ignore the latter by method, at most the computer does not ring. If it's a motherboard, take it and fix it

3: If the computer rings when the memory module is installed, remember it. The chassis is running normally, the keyboard light is flashing, and it's okay to unplug the graphics card and wipe it

This is simple, I guess the memory is loose, plug the memory from the new one, take a look, remember the answer.

Landlord This is because the memory module in your computer host is not plugged in well or there is too much dust Solution Open the host Take off the memory module Turn on the hair dryer Use a cold air to blow the card slot Use an eraser to wipe the metal sheet on the memory If you don't have an eraser, you can also use a paper towel to reinstall the memory stick and press The buttons on both sides must be buckled to be considered tight, if not, change to another memory module slot Each host has 2 memory slots.

First look at the graphics card to see if there is a problem, then troubleshoot the memory, and finally take the battery off the motherboard to discharge the motherboard.

If it still doesn't work, it is recommended to go to the repair station.

If the drops are the same length, it may be a memory contact problem, unplug the memory module with an eraser gold finger, plug it back... Or clean up the dust.

I used to be like this when I used Dell, and the last sound seemed to be a little longer, didn't it? It should be a system problem, reinstall it.

If the memory module is faulty, let's replace it.

The problem of the motherboard of the computer host, this problem needs to go to a professional computer repair station for testing and repair, and only after the detection will you know what the fault is.

Buckle the CMOS battery and reinstall it Try What you said is too general, I don't know what the situation is, the ghost knows what the red light and green light you are talking about, but generally speaking, the red light is the hard disk light, the green light is the power light, and the red light is not on, which means that there is a problem with the hard disk line.

There is no drop on the boot, the hard drive does not self-test, and your hard drive should be finished.
