The computer can t turn on, and the host keeps ringing, is it a hard disk problem?

When the computer is turned on for self-test, the small speaker in the machine will emit a variety of kinds"Toot"sound, actually, this is to us"Pour out your heart and report the self-test information. Different BIOS,"Toot"The meaning of sound is also different. Listed below are two common BIOS ons.

Machine self-test sound information.

1. AMI BIOS

1 Short sound, memory refresh failed.

2 short sound, memory ECC check error.

3. Short sound, the self-test of the system basic memory (the first 64k) failed.

4. Short sound, the system clock is wrong.

5 short sounds, CPU error.

6 Short sound, keyboard controller error.

7. Short sound, the real mode of the system is wrong, and it cannot enter the protection mode.

8 Short sound, showing memory error (e.g. showing memory corruption).

9 Short-sound, motherboard flash ram or EPROM verification error (e.g. BIOS corrupted by CIH).

2. Award BIOS

1 Short sound, the system starts normally.

2 short sounds, regular errors. You should go to CMOS Setup and reset the incorrect options.

1 long 1 short sound, RAM or motherboard error.

1 long and 2 short sounds, display or graphics card error.

1 long and 3 short sounds, keyboard controller error.

1 long 9 short sound, motherboard flashram or eprom error (e.g. BIOS corrupted by CIH).

Uninterrupted long"Toot"sound, the memory is not plugged in properly or the chip is damaged.

The monitor is not properly connected to the graphics card.

Repeat short"Toot"sound, the power supply is faulty.

None"Toot"There is no display at the same time, and the power is not connected.

If you can confirm that this "tick, tick" or "de, de" sound is emitted by the hard disk, then it means that the hard disk is close to being scrapped, and the important information in the hard disk should be copied as soon as possible, just in case.

It could be that the line has hit the fan.

It is not necessarily possible that the memory is loose.

As soon as the computer is turned on, it makes a buzzing sound, and I didn't care about it at first, thinking that it would start normally, but I found that it couldn't start, and even the sound was getting louder and louder, and I was worried about whether it would be **, how to solve it? The following is a solution that I have compiled for you that the computer host buzzes and cannot start, I hope it can help you!

The solution to the problem that the computer host buzzes and cannot be started

Some hardware of the host is caused by poor heat dissipation, in this case, you should open the host yourself to try to see which part is overheated, first prepare some tools to open the host.

Listen with your ears to see which hardware is making the sound, and then use your hands to see which parts are overheating.

If it's caused by CPU overheating, you may want to replace the fan. If the memory card makes a sound, it may be that there is a problem with the contact card slot, and the fault is that there is too much dust on the card, and the dust should be brushed off with a brush; If it is a problem with the graphics card, see if the fan of the graphics card is not working, you may need to replace the fan of the graphics card over the graphics card; Clean the dust of the motherboard and various parts with a brush, leather tiger or hair dryer;

If you can't hear it, or if the parts aren't overheating, then use your hand to the chassis to see which part has the strongest vibration, such as the power supply and the hard drive.

If it can't be checked all the time, it may be that there is a problem with the computer BIOS, or the hardware information in the BIOS has been changed by poisoning, if so, you have to find a professional to check and solve it;

Solution 1 for the monitor to turn on for a long time before it turns on:

It takes a long time for the display to light up after powering on, which proves that the display hardware is faulty, and its circuits and components should be specifically investigated

1) Check whether the filter capacitor at the output end of the power supply is damaged, if it is bulging, replace this capacitor.

2) Use a multimeter to measure the 12V resistance to ground on the main board of the monitor and confirm its value.

3) Check whether the filter capacitor at the 12V output is bulging or bursting. If not, disconnect the 12V power supply of the high-voltage board, and then test it, if the resistance to the ground is still 0, then replace the 12V output filter capacitor, if it is normal, then check the high-voltage strip part, to see if it is caused by a short circuit.

Secondly: 1 It may be that your graphics card driver is broken, update the graphics card driver.

2. Unplug the memory, use an eraser, and press it again.

3. Reload the system. (I've encountered this once, ok after reloading).

If it doesn't work, then find after-sales.

Solution 2 for the monitor to turn on for a long time to turn on:

This is caused by leakage of the visor header and the header must be replaced. When the back cover is removed, you can see a small circuit board at the end of the picture tube, and the tube socket is soldered to the circuit board. Carefully unplug the board, solder the header, go to the electronics store and buy the same header, and solder the header back to the board.

At this time, do not rush to put the circuit board back, first find a small piece of sandpaper, and carefully wipe the pins protruding from the end of the picture tube with sandpaper. In particular, pay attention to the oxide layer on the pins, if you don't wipe it cleanly, it will soon become old**. Put the board back in and you're done.
