As soon as it gets to 12 p.m., my computer makes a clattering sound30

**Out of the voice? In addition to the speaker, the computer can make sound, that is, the fan and the hard disk, excluding the speaker, the fan does not seem to ring regularly, then it is the hard disk You check whether your anti-virus software is set to 12 o'clock regular virus check or regular upgrade, it may be that the anti-virus software is running again, causing noise in your hard disk workload

Isn't it....Someone's playing a prank...I remember a kind of trickster who specialized in this kind of boredom...I've also tried pulling....You**Super Bunny, see if there is anything suspicious about the self-starting project, and if there is, cancel it....I hope you succeed in your troubles....

Come at 12 o'clock!! It's terrifying!!

Clean up the dust and see if the hard drive is ringing, if there is a problem with the hard disk, it will be troublesome.

There is that kind of virus that attacks at the end of the time, it seems to be very old, and you should be fine if you patch the system! I'm afraid of the hard drive problem upstairs upstairs!

The landlord changes the system time at another time (such as daytime) to try (change the time to 23:59 during the day) at 00:00 to see if she will come to ......

I don't want to believe in this evil.,It's almost 12 o'clock to turn off.,Turn it on after this point.,See if it sounds? When you come back to me, I like to challenge difficult problems.

This question is a bit kb. I'll just take 2 points.

Hee hee, hee hee, hee ......hee

Find yours.

It's really scary. Be careful, landlord!

Hello, one, see if there are magnetic objects at the sound edge of your computer. Second, the computer fan has less oil, refuel. Three,Open the **control panel,Except for the first one,All the others are closed,I guess the sound of sound reflow is too loud。

Hope it helps, good luck!

。。。It should be a broken horn.,Or a problem with the driver.。。。

It's a problem with the system, I just reinstalled the system.

Personal experience: Your computer should not have been cleaned internally for a long time, and it is dirty inside, so it is recommended to open the case every once in a while to clean it.

Your computer is old, with small memory, poor CPU, and struggling to run programs, like a tractor that is about to die!

Based on my years of experience, it should be the sound of the hard drive, and you can go and listen to it.

1 all first judge where the sound is coming from,There are three ** in the book,1,Speaker,2,Hard disk,3,Motherboard inductance,If it's a speaker,That's interference,It doesn't matter if the sound card is good or bad.,If it's a hard disk or inductance,You need to pay attention.,It may be a precursor to breaking.。

The sound of the hard drive, are you Lenovo's Ben?

The first possibility: because the speaker's paper cone exceeds the vibration limit, please turn down the volume.

The second possibility: the speaker is not of good sound quality.

Either there's a problem with the computer's microphone, or there's a problem with the hardware of the laptop!

If you still have a microphone, try changing your headphones.

This is the result of a discharge at the high-voltage cap on the CRT of the display.

Because the high-voltage cap on the CRT is mainly due to moisture, it is a kind of sound produced after high-voltage discharge. And accompanied by a strange smell appeared.

General treatment method: turn off, discharge first (if you don't discharge, (don't blame me for not saying it) may be shocked by high-voltage electricity!) Reassuring, but not life-threatening.

Because the current is not high), and then use a hair dryer to dry this part, it is best to use a kind of arc extinguishing glue and coat it around the high-voltage cap. Then power on and it will be fine.

Neither of the first two is entirely true. It should be that there is too much dust on the picture tube, which absorbs moisture in the air, and the insulation decreases, causing high-voltage discharge, and there is a sizzling sound. After turning on the machine for a period of time, the discharge place heats up, the insulation returns to normal, and there will be no sound.

It is recommended to take it to the place where the household appliance is repaired and do an insulation treatment. There are no problems with the hardware part.

Your monitor is an old-fashioned CRT, right?

CRT ballasts may be damp, and it would be better to open the back cover of the monitor and use a hair dryer to blow on it.

The premise is that if you don't understand, don't open the lid, there is a high-pressure package inside.

You should be a CRT monitor, it's the monitor is damp, and the high-voltage bag behind the picture tube is broken, just change it, about 30 pieces.

There is a sizzling sound behind a computer monitor for the following reasons:

1. Poor contact of the power supply of the display.

2. Poor contact of the internal components of the display.

3. If a component of the display is overheated, it may be melting This situation is more dangerous, so check it quickly.

Solution: 1. Unplug the power cord and plug it back in firmly.

2. Step 1: If the problem continues, please take the monitor to a professional for repair3. Replace it with a new one.

Perhaps it may be the cause of tinnitus.

Symptoms: Sometimes you hear various sounds such as buzzing and squeaking in your ears, and there is no corresponding sound source in your surroundings, which is commonly known as tinnitus. Tinnitus manifests in a variety of ways, some are unilateral or bilateral; Some appear intermittently, while others continue to occur; Tinnitus is felt only when the light is quiet, and noisy and restless when the heavy is working.

The onset of tinnitus may be related to fatigue, sleep, menstrual cycle, emotional factors, blood circulation status of the head, and hypoxia of the inner ear.

2.Causes: Common ear diseases that cause tinnitus include otitis externa, cerumen embolism, acute and chronic otitis media, etc., and some systemic diseases such as hypertension, hypotension, diabetes, anemia, malnutrition, etc. can also cause tinnitus.

In addition, tinnitus and hearing loss can occur with excessive use of drugs that have toxic effects on the ear, such as gentamicin, streptomycin, or kanamycin.

A computer poisoning is recommended to be antivirus.

Two Some of the software used is not up-to-date and needs to be updated, check for updates or uninstall especially some entertainment software.

3. System failure (not very likely).

Fourth, hardware issues.

Kill the virus first, and if it still doesn't work, reinstall the system.

You report the configuration or model of the computer.

When the logo appears on boot, press F10 to enter the BIOS to detect the memory of the hard disk, it takes about 2 hours, if the test results are pass and succence, then there is no problem, basically sure that it is a problem with your system. As for the bang, I suggest you listen to the hard drive closely, it should be the sound that the hard drive is emitting. Joining the detection is normal, but after doing the system, you can still go to the after-sales service, which is a hardware problem

You can set the control panel to classic view, then go to the control panel, find the IDT Audio control panel, turn off "Enable Power Management" and take a look and it should be solved!
