Boot alarm One long and two short No sound after unplugging the ATX 12V The monitor is always black

One long and two short – the wrong monitor or graphics card. Check the graphics card first, if your graphics card is fine, then it is possible that the monitor is not in good contact or the monitor is broken.

1 Short The system boots normally.

2 Short General error, please go to CMOS setup to reset the incorrect option 1 Long 1 Short RAM or motherboard error.

1 Long 2 Short Display error (monitor or graphics card).

1 Long 3 Short Keyboard controller error.

1 Long 9 Short Motherboard FlashRAM or EPROM Error (BIOS Corruption).

Constant long sound The memory plug is unstable or damaged.

Ringing non-stop The power supply, monitor, and graphics card are not properly connected.

Repeated short rings Power failure.

No sound, no display, power failure.

In other words, your computer problems will only be related to the monitor and graphics card, and it is useless to replace other hardware.

It has nothing to do with the motherboard!!

If you're okay with your graphics card, that's your monitor problem. I have had a problem with my computer monitor, and the contact is not good, just move the latch.

Unplug the ATX 12v of course it doesn't ring, the CPU doesn't work anymore, how can it ring?! If you confirm that there is no problem with your graphics card and that it is installed correctly. Then replace the motherboard or power supply.

It is caused by poor contact between the cable of the graphics card and the motherboard. Just reconnect.

It's memory, it's either incompatible or it's broken.

Check to see if any metal or screws are touching the motherboard.

Graphics card and memory, use the gold finger to eraser, and the memory can be changed to a slot.

Plug the memory module in and take a look.

Use a rubber sassafras to rub the gold finger of the memory and graphics card (the copper sheet in contact with the motherboard) vigorously, and then install it again.

One long and two short is a graphics card problem.

There is a problem with the graphics card, and the capacitance part of the graphics card is broken, that is, it is broken. If it's a notebook, there's a problem with the motherboard, specifically there's a problem with the graphics card on the motherboard.

Clean up the gold finger of the memory module. If that doesn't work, clean up the gold finger of the graphics card.

Hello,One long and two short is that the display adapter self-test failed,That is, there is a problem with the graphics card,Please check whether the graphics card is plugged in,Is there dust in the graphics card slot causing poor contact,You said earlier to unplug the graphics card and use the integrated graphics card,It's obviously a problem with the independent display,Please check it according to what I said earlier,If it doesn't work, the graphics card is burned,Please send it for repair or replacement。

Hope it works for you.

Problems with the graphics card.

1 Short The system boots normally.

2. Short: There are incorrect parameter settings in CMOS setup.

1 long and 1 short: There is a fault in the memory or on the motherboard.

1 long and 2 short: There is a problem with the monitor or graphics card.

1 long and 3 short: The keyboard controller on the motherboard is faulty.

1 long and 9 short: the motherboard BIOS chip is faulty.

Multiple long beeps: The memory module is not plugged in tightly or is damaged.

Repeated short beeps: The power supply is faulty.

The problem with the graphics card, the color is not correct to see if the line is broken, or the socket has a crooked pin. Generally, the motherboard self-test doesn't seem to be able to find the side of the monitor, even if you don't plug in the monitor, it can be turned on.

Find a friend's graphics card and try it out.

Problems with the graphics card The interface between the graphics card and the motherboard or the interface between the graphics card and the data cable is broken and disconnected.

Graphics card issues. The graphics card is not plugged in. After unplugging the graphics card, wipe the gold finger part, reinstall it, and you can solve it.

Look at the VGA head of the monitor to see if the pins are broken or crooked (especially the first one in the middle row).

The alarm is normal, the general host will dismantle the alarm, and it may be that the last abnormal shutdown caused the graphics card to not stop working normally! It's okay.

See if the graphics card isn't plugged in.

One long and two short?

That's SOS, speechless.

1 Long 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 2 Short: Wrong monitor or graphics card.

You may have burned the AGP slot of the motherboard, and that's it. If the graphics card is good, it must be a problem with the motherboard.

What the hell? -

It's really not possible to change the phone speaker, it's too weird.

This is a problem with the graphics card or monitor. You first make sure that there is no problem with your cable (such as loose), and wipe the graphics card interface and slot to ensure that there is no dust or oxide film. Look at the indicator light of the monitor again, whether it is normal or not, it is a problem with the display.

Normally, there may be a problem with the connection between your motherboard and the monitor.

How do you think of the first thing that doesn't come to mind.

Graphics cards generally don't cause such alarms.

Let's change the memory.

1 long beep 2 short beep: Wrong monitor or graphics card.
