Every time my computer boots up, it automatically restarts a few times before it can be turned on, a

You may have something set up wrong, or something is broken.

Reasons: 1. Computer hardware preheating.

2. There is a bug in the motherboard.

3. Poor memory contact.

4. Graphics card desoldering.

5. The north bridge of the motherboard is desoldered.

6. Power supply problems.

7. Motherboard BIOS problems.

Solution: 1. Use win+x shortcut keys to open the menu and select the control panel, as shown in the figure below

2. In the window that opens, click "Hardware & Sound", as shown in the figure below

3. Click "Change the function of the power button" under "Power Options", as shown in the figure below

4. Click "Change settings that are currently unavailable" in the pop-up window, then remove the tick in front of the first item "Enable Quick Startup (Recommended)", and click "Save Modification", as shown in the following figure

There are many kinds of hardware problems that cause your computer to keep restarting, such as lack of power output, high CPU temperature, corrupted cache, loose graphics card, and more.

1. It may be that there is an incompatibility between the system or programs, press F8 to move to the advanced option when you boot up, and select "The latest correct configuration" to enter the repair, and it is not possible to press F8 to enter the safe mode to restore the system or reinstall the system.

2. The CPU or other hardware temperature is too high, and the memory and graphics card are incompatible or faulty.

3. If the hard disk has bad sectors, please use the system's built-in functions or software to repair the disk, or format the hard disk to repartition and reinstall the system.

4. Power failure and voltage instability can also cause automatic restart.

5. Incompatible drivers can also lead to restart.

6. Failure of motherboard parts.

Processing: Rapid power on or off or reboot will generate extremely high instantaneous induced voltage in the circuit of the power supply, that is, there will be a surge phenomenon, which will damage the power supply and the motherboard.

The magnetic head and disk surface of a typical Winester hard disk are separated and will not be contacted, but at the moment of instantaneous boot or restart, the disk surface and the magnetic head will briefly contact each other, which will produce physical scratches, and similarly, the data in the disk cache cannot be written to the disk, or the data written to the disk is wrong, resulting in soft bad sectors.

If it's an SSD, it's just data loss, and there's nothing wrong with it. In the long run, the power supply circuit of the motherboard will be the first to be impacted, but it is far less harmful than high temperatures. Today's motherboards are very self-protecting.

The second is the hard disk, which will generate hard bad sectors in some places.

As for saying that the capacitor is burned out due to rapid charging and discharging, I disagree. It should be that the inductor in the circuit will burn out when the induced current is generated in the rapid voltage change, and the instantaneous maximum value breaks through the breakdown voltage of some components in the circuit (such as diodes). <>

You check if the fan is damaged, if something is a heat dissipation problem, it will automatically restart after turning on the machine for a while.

1. Viruses in the computer.

2. The system file is corrupted, and it can be solved by reinstallation.

3. If the CPU fan does not rotate or rotates slowly, the machine will be started, and it can be solved by changing a fan.

I've had this problem before, and I'm just fine with a memory stick! I don't know if you're like me! Find a memory module to try ha!

Wheat Lang. 63 is interesting! See if you press the reset key to the inside and don't come out, if not, try pressing F8 in safe mode? If you can enter the system, then you can my computer properties - advanced - boot and failure recovery auto restart cancel hook.

Ask win7

Question: After the computer presses the start button, the fan is rotating, but after more than 10 seconds, the fan stops rotating, and then restarts, and then repeats the above phenomenon, but it cannot be started successfully.

Question: Press f8 did not solve the problem, and the screen does not appear on the boot screen to answer, then it is basically determined that it is a hardware problem now. After powering off and disassembling the computer, unplug the memory module and power cable on the motherboard. After that, keep pressing the power button to discharge. After that, connect the memory to the power cable.

The motherboard power cord is this.

Have you changed anything recently, such as drivers, or installed any software?

1. Restart the computer, press F8, and the selection menu will appear.

2. Select the last correct configuration, try the safe mode, if you can enter the safe mode, you can uninstall the recently installed software or driver.

3. If this is still the case, you can only redo the system.

Coincidentally,I also encountered this trouble today.,Ann did what others said.,I went to the computer repair point to buy a Windows CD.,It's not expensive.,And then put it in the machine and operate according to the prompts.,It's a little slower to install.,Three or two clicks to get it.。

There's a void in it, try to plug and unplug the things in the chassis, if it doesn't work, just redo the system.

What's wrong with the computer screen repeatedly blacking out.

Causes:

1. There is too much dust in the computer, which causes a short circuit in the motherboard, but this phenomenon occurs a lot in cold weather.

2. The computer CMOS battery is aging, try to replace the battery.

3. The power supply itself is faulty, or the voltage is too low, etc.

4. The quality problem of the motherboard itself is actually similar to the first situation.

As far as I know, the biggest possible reason is that the power supply is not working. Or the hard disk needs to be serviced. The failure to boot is estimated to be due to the sudden failure of the hard disk to work during the boot process.

Causing the file to fail to be read. Or a memory issue, most likely a power issue. The power of the power supply is not enough.

The boot phase of a computer consumes a lot of power. The instantaneous power is relatively large.

When the weather is cold, keep the indoor temperature above 20 degrees for half an hour and then turn it on.
