The P4 CPU temperature is too high and the buzzer squeaks

I'll also say that I also had this issue a while ago, but it's solved now:

A few nights ago, I played overclocking, cooled a little, after a period of time (the machine has been on for a long time before overclocking), I feel that the temperature in the case is very high, the CPU radiator and the north bridge are very hot, a little suspicious of the poor thermal conductivity of silicone grease, so I shut down and remove the radiator and reapply the silicone grease again, and then turn on the machine, the problem mentioned above appeared, it was still very quiet when nothing moved, and the CPU ran something near the motherboard CPU will make a sizzling sound, I don't understand, the motherboard that I just bought not long ago will not have a problem??? I looked around the motherboard for a long time and didn't find anything wrong with the **, which is troublesome, and I won't run the computer city again (it's far away, and it's jammed all day, Guangzhou Pacific Computer City)? I reinstalled the CPU cooler again, and the problem is still the same.

Reloaded n times again, and it's still like this. It doesn't seem like this phenomenon has ever happened before, but why did it ring all of a sudden?

The question arises:

After n repeated inspections, I removed the entire motherboard and observed it in the most detail, ha, I finally found the hiding place of **. The CPU heatsink has four fixed points fixed on the motherboard (I use Intelr CPU, the original fan), and one of the fixed points is not completely stable (I also removed it to know that something was stuck that caused the previous n times not to install the heatsink, because every time I install it, I will shake it with my hand, it is very stable, I also think it is very strange), remove the heatsink and reinstall it (sweat!). I watched it a few more times.

This time it's absolutely installed), and then connect the wire, turn it on, ha. Ha. Finally solved the problem.

After a night of repeated inspections, I think that it should be the CPU (or other chips with high heat) and the heat sink are in poor contact (not excluding the thermal conductivity problem caused by the dry silicone grease) to cause this strange sound (sorry, I don't know how the sound is made, it's not good to guess), it should be noted that poor contact does not mean that there is no contact at all, and when there is a problem, I have also touched the CPU heatsink with my hand and also seen it in the BIOS, which is similar to the usual temperatureOn the surface, it's hard to spot this problem. If the chip and heatsink are in good contact, but the motherboard temperature is too high due to other factors, the above problems may also occur, you can find a way to reduce the temperature of the motherboard before making other plans.

My issue proves that the CPU and heatsink are in poor contact, and the above is purely a personal opinion.

The P4 is known for its temperature and power, and the CPU heatsink is replaced, and the Cooler Master is replaced.

COMS sets the temperature alarm to be adjusted upward.

The fan is broken, so get a better one

The CPU is coated with silicone to help dissipate heat.

The simple way to do this is to go to the BIOS to modify the CPU temperature alarm settings, i.e. increase the temperature to!

1. Check first to see if there is moisture between the cooktop and the bottom of the induction cooker. If there is water between the two, there will be a loud humming sound when the power is turned on.

2. If it is determined that the sound is made by the internal heat sink of the furnace, it is the sound made by the IGBT power tube. Because the induction cooker only has a large heat sink, it is used for heat dissipation of the power tube. This can only be solved by replacing the power tube.

However, it is not recommended to replace it privately, first, the quality of the power tube on the market is uneven, and secondly, after all, the factory parts have been tested by the factory, and the operation is relatively stable, and the sound is only a little loud, which does not affect the use.

3. Another one is the cooling fan, if there is a lubricating oil filling port, just drop a few drops of lubricating oil, which can be temporarily solved. The fan can also be replaced.

I didn't sense that there was an iron pot on it.

You're a bit of a mess, my opinion.

1. The motherboard has a centralized display and a separate graphics card, and it stands to reason that the integrated graphics card should be turned off in the BIOS, so normally, there will be no signal if you directly insert the integrated graphics interface.

2. Since you have removed the motherboard battery, the BIOS should be restored to the default value, and the integrated display should be turned on, so you can unplug the independent graphics card, connect the integrated graphics interface, and turn on to see if there is a signal.

3. After booting up, pay attention to the hard disk indicator light or listen to the sound, if there is a disk reading operation, the machine has entered the system normally, but it is not displayed.

4. If the display is not displayed when the independent graphics card is connected, it is likely that the graphics card is in contact with the problem, it is recommended to clean the gold finger of the graphics card, unplug and unplug it several times, and try it repeatedly.

5. If there is still no result, it is recommended to use the replacement method to check one by one, or send it directly for repair.

If it can be started directly on the integrated graphics card port, you can try out the graphics card, generally this kind of problem has, memory, power supply, graphics card, motherboard. But you can quote 800 for brand machines.

Squeaks should have a long and short rhythm, right?

The graphics card fan is too noisy, and there should be a problem with the fan. Either the fan blades are defective, or the lubrication is poor or the assembly is loose, please check carefully. If the fan blades are defective, it is best to replace the fan; If the lubrication is not good, you can add a little lubricating oil appropriately; If the assembly is loose, it must be reinstalled.

If you need to replace or reinstall the fan, you must first remove the old fan and take special care not to damage the graphics chip and surrounding circuitry. When disassembling the fan, it is best to put a small amount of organic solvent on the connection between the fan and the chip, leave it for a minute or two, and then use your fingers to pinch the fan to move back and forth in the horizontal direction, and then carefully remove it.

The reason why the graphics card makes a sizzling sound:

1.There is electromagnetic interference next to the sound output device;

2.Aging of sound output equipment;

3.Sound-related hardware acceleration setup issues.

Easy Steps]:

Solution]:

Solution 1: There is electromagnetic interference next to the sound output device, poor contact of the audio interface, etc., such as: mobile phone interference, the speaker interface is not firmly plugged in, etc.

Solution 2: The sound output equipment is aging, and if the sound is too loud, it will emit a whistling sound, and the sound output equipment such as the sound output device will be replaced.

Loose or dusty ... Clean it up.

It's normal for fans to be loud when running large programs or games. This is due to a technology, that is, when the system runs some small programs, the CPU will work at reduced frequency, for example, it may work at a low frequency, the CPU works at a low frequency, and the natural fan does not need to run at full speed, at this time, the sound is relatively small, when running a large program, the CPU runs at full speed, the fan will also run at full speed, and the sound is naturally slightly louder. However, we can't tell if the fan sound you are talking about is normal based on your text description, if you feel that your fan sound is really abnormal, it is recommended that you contact HP's repair center to check and see if the fan is faulty.

The squeaky sound that came out there? Chassis? Loudspeaker? You adjust the volume to see if the volume is small and there is no abnormal sound, it may be a problem with your sound card or audio, my computer has just been replaced with an inferior sound card, and there will be noise when the sound is amplified.

, check the speaker plug, and there may be a source of interference near you. And also... Hard disks have bad sectors. Hopefully not!

The battery is dead, or this watch has not been used for a long time, so try to turn the gear more often.
