What is the reason why the computer won t turn on, or it has to be restarted several times before it

bios rom error?BIOS memory error?

Boot long beeping is generally a memory problem, change a slot first, can't solve the problem, just change the memory to try.

There is also the possibility that the power supply is insufficient.

There should be a problem with the memory, and I also have such a situation today, just change the position.

I've had a similar situation with my computer before, and mine is a motherboard failure, and of course, in general, the memory may be larger

The rest of the possibilities are very small, hehe

Mainly check the memory and motherboard handles

The motherboard capacitor may have burned out.

Reasons and solutions for computer not turning on:

Step 1: First of all, according to the specific situation analysis, if there is no power response directly, then check whether there is a power supply, poor contact, hardware and other problems, go to the second step, if it is not possible to enter the system may be operating system or software problems to go to the third step.

Step 2: Check whether there is a power supply problem, first see if the power supply is not plugged in well or there is a problem with the plug, if you are using a battery, then plug it in and try again. You can go to a friend or go to a computer repair shop or sales store to find the same model of power supply to try it.

After replugging the power supply, press the power button again, and if it still can't be turned on, then press it for a while. If you change someone else's power supply to turn on, it means that there is a problem with the power supply, if it proves that there is no problem with the power supply, it may be the hardware reason, go to the fifth step.

Step 3: Go to the last correct configuration to adjust, turn on and press and hold F8, enter the advanced options page, select "The most recent correct configuration", and press Enter. If it can enter the system, it may be caused by viruses, incompatible hardware drivers with the system, or operating systems.

After entering the system, run the anti-virus software, check and kill the virus, if there is a virus, restart the computer after the anti-virus, if it is not normal, it may be caused by the incompatibility of the device driver and the program, delete the graphics card, network card and other drivers, restart it after removing the driver, if there is still a problem, then go to the next step.

Step 4: Repair and install or reinstall the system, set "Optical Drive as the first boot device" in the BIOS, then insert the system disk, and press the R button to perform "Repair and Installation". If the fault persists, just at the beginning of the system, select "One-click GOST to restore the system" or use the system disk to reinstall the system.

Unplug the power cord, remove the computer battery, wait a few minutes, and then put the battery back in.

Press and hold the computer's power button for about 5 seconds until the computer shuts down.

Then press and hold the power button again to see if it can start normally after turning it on.

If you are still having problems, repeat steps 1 and 2 again, about 3 times.

If none of the above methods can solve the problem, some hardware repair may be required, and it is recommended to seek professional help.

Hope the above information is helpful to you.

Here are the possible workarounds:

Check that the power supply is properly connected and turned on, and make sure the power cord is plugged in tightly.

Check that there are any loose hardware devices or plugs inside the computer, such as memory modules, hard disks, or graphics cards, and plug them back in.

If you can access the BIOS, check that the computer boots in the correct order and make sure that the main boot device is a hard drive.

Try to enter safe mode and do a system repair.

If none of the above methods work, consider using a system recovery disk or reinstalling the operating system.

If your computer still won't boot, it may be a hardware malfunction that needs to be repaired or replaced.

Check that the power cord and power plug are connected properly to ensure that the power supply is normal.

Check whether the internal hardware of the computer is loose or damaged, such as memory modules, hard disks, etc., and needs to be replugged or replaced.

Check your computer for viruses and use antivirus software to scan your entire computer.

Try to enter safe mode, press F8 or other shortcut keys to enter safe mode, and perform system repair or reinstallation operations.

If none of the above methods can solve the problem, it may be a hardware failure or system crash, and you need to seek help from a professional repairer.
