After completely cutting off the power supply, replace the memory module.
-
It's not plugged in, otherwise the computer is incompatible.
-
One possibility is that it is incompatible, and the card slot has not been used for a long time, and the copper sheet has been oxidized, clean up the card slot, and wipe the copper sheet on the memory module, I hope your problem can be solved.
-
A lot of fakes in Kingston It's also possible that you didn't plug it in.
-
It is recommended to add the same size as the original if you add memory, otherwise it is easy to have problems.
-
It is most likely due to the fact that the memory module is not compatible with the computer.
When purchasing a memory module, you should pay attention to:
1. What kind of memory module to add depends on what the original memory of the computer is. The most important consideration for expanding memory is compatibility.
2. Pursuing high clock speed too much without considering compatibility issues will lead to unstable memory or failure to boot.
3. It is more appropriate to use the original memory module version to slightly increase the memory module capacity value.
-
It may be incompatible, you can use a single 2G one, 3G is completely unnecessary, it will bring a lot of instability factors.
-
It is because the new memory module installed does not meet the requirements of the computer, so it cannot be started normally, so it cannot be turned on.
Learn about memory module information.
1.Click "Ctrl+Alt+del" on your keyboard to open the task manager.
2.Click on Task Manager Performance.
3.Click Memory. You can view the memory size and specifications. It is convenient to buy the correct model of memory module.
Precautions for installing memory modules.
1.Before installing the memory module, turn off your computer. It is better for the computer to shut down naturally than to remove the battery directly.
2.Turn off the computer and remove the battery. Removing the battery is a form of protection for the installation of the memory module. After the installation is completed, connect the battery.
3.Once the memory module is installed, plug in the battery and tighten the screws. If it is not tightened, the screws will loosen in the future, the battery will loosen, and the power contact problem will cause the computer to not turn on normally.
-
It doesn't look good, maybe you have the wrong memory model, or you plugged in the wrong memory module or socket and it burned out.
-
Memory compatibility problem,Try a single plug in a 2G,If you can, sell the 1G one,If you mix it,The actual speed is not as fast as a 2G。
-
1. It may be that the memory module you purchased is not the right model, you look at what model your original memory is, and the frequency must be the same before it can be used.
-
It may be that the motherboard capacitor burned out when you plugged it in for the first time, and there is also a possibility that the memory module you bought later is not compatible with the original one.
-
See if it's reversed, and then you see if the 2 memory sticks are the same.
Don't make a different one ... Be careful, the motherboard burns.;
If the computer is 6G, the XP system is useless, and if you want to use 6G, you can change to a Win7.
-
I haven't heard of the old memory brand, hehe, it is recommended to unplug the old memory and try it with only the new memory.
-
1 x 667 1 x 800 Even if the brand is the same, it may not be compatible with DDR2, among which Kingston, ADATA and Apacer can be matched like this, basically no problem, your brand is not well-known, and it must be average in technology. Incompatibility is also nothing new. It is recommended that you sell the old one, about 80 to 2 hands, and the computer sells very well.
2G is enough, you don't have to have 3G

You must first dress up to make sure that your memory card is not damaged If you are damaged, you can say nothing, go directly to the technology market to buy a new one, and now the memory card is also cheaper, and the 200 yuan of miscellaneous brands is very stable. If there is no problem, then open the main cover, you can see a fan, there is a long bar on the side of the fan, that is, the memory module, there is a white fixed button next to it, open half-open to both sides, and the memory module can be easily taken out. There is a long row of golden things under the memory module, we teach him the gold finger, the material of the gold finger will appear oxide film at high temperature for a long time, resulting in poor contact, the computer can not start, take the memory module down and erase it, wipe the eraser debris with toilet paper, and then install it according to the method of removal, the computer should be able to start.
Pay attention to whether there is an alarm sound, there is an alarm sound indicating that there is still a problem! This will have to wait for professionals to repair, and it is best not to move Note: The above disassembly method is to turn off the power supply and do not use it when it is turned off!!
The technology is limited, hope it helps you, thank you.
-
Poor contact: Erase the metal finger part with an eraser or white paper.
Bad compatibility: change.
-
Wipe the gold finger with an eraser first, and then insert Kingston's separately to see if it can light up.
Otherwise it's a problem with the memory module.
-
The 2 memory modules are not compatible Make sure that you are not buying a fake.
-
Swap it out and see. If the memory module in slot 1 does not work, the memory module in slot 2 will not turn on. Oh, maybe it's incompatible, depending on whether it's DDR2 or DDR3 and whether their frequencies are compatible.
-
If compatibility issues occur, we recommend that you use a single memory or two memory of the same specification.

1. Unable to boot normally.
Tips: There are three main ways to solve this kind of phenomenon: first, change the location of the memory, which is the simplest and most commonly used method, which is generally to insert the low-speed old memory in the front position.
Second, on the premise that the computer can be basically booted, go to the BIOS settings, and set the memory-related settings according to the specifications of low-speed memory. For example, use one of the memories (if [url="The memory of DDR333 and DDR400 is mixed, it is best to use the memory of DDR333), boot the computer, enter the BIOS settings, slow down the working frequency and reaction time of the memory, and then shut down and insert the second memory into the second memory after the old memory can run stably.
Poor. 2. The computer is unstable.
Tips: This kind of problem is mainly caused by memory compatibility, and the basic idea of solving it is basically the same as the above. First, change the location of the memory.
Second, turn off the option in the BIOS for memory to be automatically configured by the SPD and configure it manually instead. Thirdly, if the motherboard is equipped with an IO voltage adjustment function, the voltage can be appropriately increased to enhance the stability of the memory.
3. The memory capacity is not identified correctly after mixed insertion.
Tips: The reason for this phenomenon, the first may be caused by the motherboard chipset itself, some old motherboards only support 256MB memory capacity (i815 series only supports 512MB), and the excess part cannot be recognized and used. Of course, there are some cases caused by the motherboard not being able to support high-level memory particles, and the only way to solve this problem is to replace the motherboard or memory.
In addition, in some cases, this problem can be solved by adjusting the order in which the memory is inserted.
The problem of unstable memory mixing and insertion is an old problem. In the face of this situation, the author recommends that when you buy memory modules, you should choose high-quality memory such as Kingston and Jintaike, because their differential branch gas compatibility and stability are relatively good, the probability of problems is lower, and the after-sales service is also guaranteed.
The other part is because of the poor contact between the gold finger and the socket of the motherboard during the use of the memory, or the problem caused by viruses and other reasons.
-
The memory is incompatible, try to unplug the next one in turn, if both can work separately, it is incompatible.
-
Is the frequency of the memory module you added inconsistent with the original, see if one of the two is 1333 and the other is 1066?
No consequences, normal use, the motherboard can be turned off HT. >>>More
