This article is to share with you what to do if the win10 computer fails to start up. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Possible reasons: there are a variety of reasons why computers can't start properly. Figuring out whether the problem is caused by hardware or software can help solve the problem.

1. First: check all cables (including power plugs) to make sure that all equipment is properly and securely connected.

2. Next, check whether the power is on. Listen to the sound of the power supply fan and see if the hard drive is working properly. If you don't hear anything, you may need to replace the power supply. To determine this, consider using a power test device, such as the PC Power and Cooling, to test the power output. Of course, before unloading the computer, you should check the power circuit breaker in the room and see if you can turn on other live devices to make sure there is nothing wrong with the circuit.

3. If the power supply is normal, but the screen is still dark, try connecting another monitor to the computer (you can borrow one if necessary) to make sure it's not the monitor. If the monitor is working properly, change the video connection cable to see, or is there no image? If the hard drive works properly at this time, it is very likely that the video card has malfunctioned. To replace a new motherboard, please refer to our article "if you replace a video card", or use the integrated graphics card of the motherboard, if the motherboard has this function. When the chassis is opened, check whether all the fans are working properly after the power supply is started, and the computer may also encounter the problem of overheating.

4. If your monitor is working properly, but the hard drive does not boot and the display does not have any images (or if you can see the image but the computer cannot boot through the self-test), consider resetting the CMOS. Turn off the computer, unplug the power, then wear antistatic gloves, etc., and remove the battery from the motherboard. Then wait about five minutes to check your PC user manual or visit the manufacturer's website for information on how to reset CMOS settings. Restart the computer after setting up successfully to see if the problem has been solved.

5. If the computer still fails to start, the culprit may be a broken memory stick. Remove one piece of memory at a time (or replace it with known normal memory) and restart after each replacement. In addition, you can create a free MemTest86 boot disk on another computer and use it to select memory sticks.

6. If the above methods do not work, it is possible that the motherboard or CPU is broken and needs to be replaced (the cost ranges from $80 to $300 or more). However, at this time, the data on the computer may still be intact, as long as the hard drive is connected to other PC hosts, you can take all the data out. Consider going to a computer repair shop to have your computer repaired, which is more cost-effective than replacing it with a new one. If you are using a laptop, the repair shop may be your best and only option.

What if the operating system fails?

Compared with the above terrible computer hardware failures, you are much more likely to encounter software problems, such as Windows not being able to start or breaking down at startup. Next, I'll show you how to deal with operating system problems.

1. Start in safe mode. Press a specified key when Windows starts to enter the startup menu and select safe mode from it. Usually, when you choose safe mode, Windows will try to fix it, then shut down and start normally. If you have Windows Vista installed, try selecting "repair your computer" from the startup menu (if you don't have this option in your startup menu, check the Vista installation CD). You will have many options to repair the brain, and "start repair" is definitely worth a try.

2. Still can't start normally? Try "Last correct configuration" on the startup menu, which is especially useful if you have recently replaced the hardware or driver. If you have successfully started the computer, replace the newly installed hardware (there may be a compatibility problem) and "return the driver" in device Manager. Right-click my computer (computer in Vista), select hardware (Windows XP system), and then select device Manager.

3, if you can start the computer in full mode, but cannot enter the system in normal mode, you can try to restore the computer settings back to the last normal working state (select "programs", "Accessories", "system tools" in Windows XP; if Vista, click "start", enter "system", and then select "system restore" from the list of programs). By automatically updating, downloading and installing the update file, your computer may become unstable, and you can change the default settings to avoid such events. In addition, you should run antivirus and antispyware software in safe mode.

4. If the computer still fails to start, there is likely to be a big problem with the Windows system. Try to start from an emergency CD such as Knoppix disc or emergency boot

CD boot, they can help you find out whether your computer can still boot or not, and copy out critical files from your hard drive.

5. If the computer still fails to start at this time, reinstalling the system may be the only feasible way. You can use the standard Windows installation CD, and all the data on the hard drive can be saved. Some PC manufacturers also provide repair CDs that can repair the system while ensuring data security, and check your user's manual to see if there are any relevant functions.

Avoid recurrence of problems: computers often break down without warning, you can: enable system restore, keep the system repair CD, prepare common programs for use when reinstalling the system, backup the system frequently, and so on.
