New memory, no response when booted, motherboard does not alarm, please ask the reason?

If the insert is fine, it's a memory problem.

What about replacing it with the original memory? Can it be turned on? If you can boot up with the original memory, it means that the new memory is not compatible with your motherboard. It could also be that there is a problem with the motherboard's DIMM slot.

Do you have one memory module or two for Ann now? If it's one and you can't erase it with an eraser, it's a matter of memory, provided that it's compatible with the motherboard. If it's two, you have to look at the compatibility of the two memory, and then it's still the problems I said before, to buy a new one, you must bring the old one.

The versatility of the memory is very strong, and it can't work on other machines, the problem should be on the sliver, learn more about the parameters of the original sliver (mainly the frequency, although the high-frequency sliver theory can also work with reduced frequency, but I have also encountered such a problem before: the original 553 can not be turned on with 800, and the 800 is normal if it is replaced by 553, I don't understand!! Go and try it according to the parameters of the original sliver!!

Try it differently. Not yet, there may be a problem with the motherboard.

However, if there is no memory, how do you get into the system?

There is no memory that will alert you.

Since you are not on site, you can't be sure exactly where your problem is, but it's best if you have the conditions to take the parts apart and test them on another machine. It can teach you simple testing methods.

Start by looking at your current symptoms. The preliminary estimate is that a part of the motherboard has poor contact.

Let's analyze your situation first: 1. The CPU fan turns to indicate that the power supply is normal, and the fan is connected to the power supply is normal. 2. If the keyboard light is not on, it means that the keyboard interface has no power or a certain part of the motherboard is open.

3. Pull out the memory and do not alarm, it means that the machine has not started at all, here is the question, after normal start-up, you will hear a "beep" sound after a few seconds, are you not? If not, it means that the judgment is correct, and it is not started at all, if there is, the memory must be alarmed, why am I so judged? Isn't it judging that your memory contacts are not good?

Because you said that other memories are connected to the light, it means that the contact is fine.

Finally, basically make sure that your power supply, memory, and graphics card (there are few problems with the board, and now it is not booted, and no signal is normal), there is nothing wrong with it, and there are only two places where there are problems. CPU or motherboard.

Has your CPU been taken off with silicone grease or dusted? Take it down to see if the pins are not right when you install it, you have the easiest test method, and try it on other machines, if it's okay, then don't ask. The motherboard wiring is not in good contact.

Find a multimeter and test it slowly, because the memory does not alarm this clue, I estimate that even if it is not a CPU problem, there is a problem with the CPU connection, because from the order of boot detection, he detects the CPU first, and then the memory, so your detection direction is also very clear.

Finally, I hope it helps you.

After turning on, whether the CPU fan and power supply fan are running, if they are not running, it is a power supply problem, and the power supply can be replaced, otherwise, see if the display is displayed, if there is, and the case horn keeps ringing, it means that the memory module is not plugged in tightly, and the memory module can be plugged in again, otherwise.

If the fan is rotated, the power supply has started, the monitor has no image, the computer cannot enter the normal working state, the computer has not passed the system self-test, the motherboard BIOS settings have not been output to the monitor, and the fault should be on the motherboard, graphics card and memory.

If there is an alarm, it means that there is a problem with the self-test. There are two types of BIOS, which are AMI and Award. Most motherboards are AWARD BIOS.

The BIOS of the award is set to:

A long and constant sound: the memory module is not plugged in tightly.

One short: the system starts normally.

Two shorts: The CMOS settings are incorrect and need to be set again.

One long and one short: Memory or motherboard error.

One long and two short: The monitor or graphics card is wrong.

One long and three short: The keyboard controller is wrong.

One long and nine short: Flash RAM or EPROM error of the motherboard BIOS.

The BIOS of the AMI is set to:

1. Short: Memory refresh failure.

Two shorts: The memory ECC verification error is incorrect.

3. Short: The basic memory check of the system fails.

Four short: The system clock is wrong.

Five short: There is an error in the CPU.

Six short: The keyboard controller is wrong.

Seven short: The real mode of the system is wrong.

Eight short: Displays a memory error.

Nine short: BIOS chip inspection error.

One long and three short: memory error.

One long and eight short: the monitor data cable or graphics card is not plugged in.

If there is no alarm sound, it may be that the horn is broken or the power supply is not good, and you can replace the power supply if you have the conditions.

Is there a beep when booted? Yesterday, I couldn't turn on the machine because of the power problem.

The fan also turns. Generally, it is not possible to power on and try to replace the component.

Memory, motherboard, power supply These three things are the main factors that cause the machine to not light up.

First of all, look at whether the CPU fan rotates, if it does not, the power supply is broken.

Look at the memory again, if there are more than one memory, then try one.

Check the power supply, it is best to use a multimeter to check it.

It may be, it depends

The computer boot monitor does not respond, there must be a problem with the computer hardware, it is best to use the replacement method to eliminate the problem, judgment method:

1. Press the upper and lower case on the keyboard. The light is on, indicating that the graphics card, monitor, and other hardware are faulty.

2. If the keyboard light does not light up, it means that it is a memory, CPU, motherboard, or power supply problem.

Solution: 1. If the keyboard light does not light up, first wipe the memory module with an eraser, and check whether the gold finger of the memory module has any burnt marks. Replace the memory in the slot.

2. Check the capacitors and resistors on the motherboard to see if the capacitors are bulging, whether there is a burning smell on the motherboard, and clean up the dust on the motherboard.

3. Remove the CPU fan, power on and turn on, test whether the CPU has a temperature change by hand, if not, the CPU is not working, either the motherboard is broken, or the CPU is not plugged in properly, and the CPU is re-plugged.

4. Power supply problem, although the power supply is powered on, but the motherboard can not work normally, replace the power supply and try it.

5. If the display card is loose or oxidized, the keyboard light will be on, the screen will not be displayed, wipe the gold finger of the graphics card with an eraser, and check whether the capacitance on the graphics card is bulging.

6. Minimize the test method, only leave the power supply, motherboard, CPU, memory, graphics card, keyboard, monitor, unplug all the wires on the rest of the motherboard, use a screw knife to short the switch pins, if normal, add the rest of the hardware, piece by piece, until the cause of the problem is found.

This is one of the bad phenomena of memory modules.

The memory is broken, there are 4 phenomena:

1. Don't turn on: The above 2 also said, there is a Weng sound when you boot up2, false bad: often enter the state of death, the picture freezes 3, poor functionality: often enter the state of death, but it is a flower screen.

4. Poor appearance: The appearance of the memory module is poor.

Clean the memory module and change the slot. Sometimes it can be a slot issue.

There is a problem with the quality of the memory module, or it may be incompatible, try to change the root memory.

8.9 out of 10 is a memory problem Find someone to borrow a root memory to try No, you should see how the CPU fan is doing.
