When the computer is plugged in with three internal memory, the fan will turn and stop! Plus sub que

Damn, it's obviously a lack of power supply. Your console's power supply is not enough to support 3 memory modules, so you should find a high-power power supply.

Do you mean that a machine with two RAM and a discrete graphics card is normal, while a machine with 3 RAM and no graphics card cannot run?

As you know, although there are only a few pieces of hardware in a computer, it is very complicated to look at just one piece of hardware. I don't think you can just look at the power consumption of memory and graphics card and conclude which one has more power and which one has less power. Taking a step back, even if the power of the graphics card is relatively large, you must also know that the memory and graphics card are connected to the motherboard, and the motherboard is originally a complex circuit board, and there are resistors on the motherboard, you know?

Therefore, adding a hardware in the computer to increase the overall power consumption should also take into account the existence of resistance, resistance is also power, maybe the memory is working with thousands of resistors on the motherboard, then you add one more memory consumption of power = memory power + power of n resistors on the motherboard, and maybe the power consumption of the resistor working with the graphics card on the motherboard is very small, in general, the actual power consumption is still a large memory consumption is also understandable.

If the disc boots, if it can't be booted, there is a problem with the disc or optical drive, or the optical drive cannot work properly due to insufficient power supply.

Motherboards generally have three memory sockets, don't plug them all in. Full plugging is error-prone. It's not necessarily the reason for the incompatibility of memory modules.

I forgot what the reason was. I guess your motherboard is very old. Because now it's basically two-socket.

There are very few three. There are three motherboards that are very early. So your motherboard memory is fine.

Originally, the motherboard supports 2 slots, and multi-plugging is useful?

You're so funny, the CPU is not installed, and the motherboard self-test can't be stopped.

The power switch cable on the chassis is short-circuited, you unplug the power switch cable on the chassis, touch the switch on the motherboard with an insulating screwdriver with an insulating handle, and turn on the machine to see if it will turn around and stop. Please be sure to pay attention to safety, please be sure to pay attention to safety, please be sure to pay attention to safety, please be sure to pay attention to safety,

You can go to the repair there and have a look.

It has nothing to do with memory modules.

First of all, there are a few issues to identify.

First: whether the CPU frequency has been set in the BIOS this time, if it is set to power max or something like that, then the CPU will always run at full speed, then the temperature will be too high, so the fan will naturally keep rotating in order to dissipate heat from the CPU, which is automatically controlled.

Second: the fan is dusty, which affects the effect of heat dissipation, so the CPU temperature has been high, so the fan will rotate at full speed to dissipate heat for the CPU.

Third: the fan into the ash, the noise becomes louder, the original is also turning, but sometimes high speed and sometimes low speed, and at low speed, because the noise is small, you don't hear it, but now it is different, the noise becomes louder, I think it has been rotating, and it is not divided into high and low speed.

Fourth: In the system, if the power management software is not installed correctly or set up with the included power management software, Intel's CPU supports frequency reduction and power saving mode, if it is not set correctly, or the misoperation is set to run at full speed, the CPU temperature will naturally be high, and the fan will keep turning.

Fifth: Some bad background programs occupy too high CPU usage, solution: when entering the system, after running for a while, open the task manager, check the CPU usage, if it is higher than 50% to see which process.

Finish the process, then wait a while and then hear if the fan is still spinning. If this is the problem, then look at the program associated with this process and delete it, or remove it at startup.

Whether this fan is a CPU fan or a power supply fan or a graphics card fan, the fan turns to have nothing to do with whether the memory is inserted or not.

All are DDR2 memory and compatible.

Install 533 Then your 667 memory will be automatically downclocked and become 533.

And you can't boot when you install new memory, and the fan turns, I personally think it's a quality problem with the memory itself.

Change the strip of 667, the frequency of 533 is not compatible with your motherboard or CPU! (The second generation of the old machine.)

Big brother, the memory is incompatible, yours is 667, and the other is 553.

You have to add the same thing, either it's 667 or it's all 553.

Generally, the compatibility of brand machines is relatively good, and the factory will test many times, but if you want to upgrade the brand machine, especially if you want to upgrade the memory, it should be noted that it is best to be a brand, and the best frequency is the same.

In view of the problems above, a few suggestions are given.

1.Wipe off the gold finger from the memory of the original machine, and then put it back in.

2.Refresh the BIOS. Restore the default.

3.Clean up the dust inside the chassis.

What does it mean to have a fan spin infinitely? Isn't it not turned on??

The memory is broken or not plugged in properly. It can't be detected.

The fan is oil-deficient, dirty, and fluffy. Although some fans use oil-impregnated bearings, after a long period of use, the same will be due to the lack of oil fan shaft, or because the dust is adsorbed on the fan blades and shafts, the computer use environment is poor, and there are fluff entangled in the shaft, causing the fan to rotate poorly, and the fan rotates and stops. You can remove the fan, clean up the dirt, open the fan shaft hole cover, add some high-grade lubricating oil or clock oil, then cover the sealing gasket, label it (don't underestimate this label, it can help seal the leather gasket), reinstall it, start it up, if it still doesn't work, just replace the fan directly.

1.If you use too much force, you will touch the pins around the capacitor or CPU and solder, and there will be a feeling that it will not be broken, so it is not surprising that the fan stops and turns.

The motherboard detection temperature of the CPU was inadvertently raised, so the motherboard did not rotate when it stabilized slightly, and it turned again as soon as the temperature was exceeded.

This is the reason for being smart, in fact, mine too, because when the CPU is not processing a large number of files, it will not be converted, and when the CPU is processing a large number of files, it will run, and it will not affect your normal work.

You may have enabled the smart fan speed control function in the motherboard BIOS options, when some programs that use CPU resources are turned off...The CPU temperature drops, and the fan stops when it drops below a certain temperature...When the temperature rises again, the fan starts again...

My fan also stops and turns, and the current motherboard seems to have smart settings that can automatically adjust the speed of the fan according to the temperature of the CPU.

It may be that the temperature is too high, or that you have a problem with the cooling fan...There are a lot of blacks now, and the new ones are not necessarily good.

Is it a voltage problem, I don't know if installing a voltage regulator can solve it.

Remove the fan and light it up!

Reboot and press F8 to enter safe mode.

The possibility of internal failure of the power supply is the largest, belonging to the power supply with immovable load, if it has been used for many years, it should be the internal capacitance reduction of the shape, there are hands-on conditions can be disassembled to see.

Try to change to a memory module of the same model, I've had this situation before. Change a memory module and you'll be fine. Or try a different slot.

If it doesn't work, deduct the battery to let the motherboard discharge, and press the battery and memory module. If this problem still occurs, you can only go to professional maintenance to test.

You can try to change the fan first, after all, it's only a few dollars. If you can't do it yourself, send it for repair. However, it is estimated that there is a higher possibility of a fan problem.

If the CPU pins are broken, you can still solder them.
