If your Windows computer won't start up don't panic because we have the following troubleshooting steps that you should take when your computer is not starting up properly.
When you want to work or play games on your computer, sit in front of the computer and press the power button like you do every day. However, one day you may encounter a problem where you press the on/off button but nothing happens. Sometimes, your computer won't turn on at all, or it may turn on and then turn off immediately.
As far as she is concerned, there is clearly nothing wrong. So why won't your computer start up before you panic or start looking for a new laptop or computer to buy? We first want you to make sure that this is not something you can fix yourself. The basic solution we have given you in this article is that you can fix this problem yourself at first (or even if you can't fix it, you may be able to determine why your computer won't turn on. Where does it come from?) What are the steps?
Add more power to your PC than ever before.
Are you sure your computer is properly connected to the power cord (or if it's a laptop, are you sure your laptop's battery isn't dead?) If it doesn't turn on and you can't even hear a sound, the fan is on, and there's no Flashing lights and nothing appears on the screen. You may have a problem with the power being supplied to your computer or laptop. Explore your computer and plug it directly into a wall outlet that you know works, instead of plugging in a power supply or backup battery that may not work. Make sure the power switch on the back of the power supply is turned on and that the power plug is connected to the power switch. Make sure the switch is turned on as well.
If you are using a laptop, make sure the charger is inserted correctly and into the correct port. If charging via USB-C, only some USB ports can provide power. A defective power supply often causes boot problems. Even if the fan and lights are on. Therefore, if the troubleshooting steps in this section do not resolve your issue, it may be time to replace your power supply.
Check your screen
If the computer appears to be turning on but you don't see anything on the screen, the computer may be turning on but the problem is that the screen is not displaying an image. Make sure your monitor is connected. (Try using a wall outlet instead of a power strip.) Turn the unit on and set it to the correct input using the buttons on the side or bottom.
Make sure that the cable connecting your monitor to your computer is not loose, damaged, or defective. You also want to get rid of screen problems. So try connecting your computer to another display or even a TV. Then check if you get the same picture that you get when you turn on your computer every day. If you can, you may need to replace your screen.
And don't make it too big of a deal. Many people ask for help with computers (especially laptops) that won't turn on. But in reality, it turned out that they had completely reduced the brightness, causing the screen to become a black screen instead of being able to display a normal image.
Listen to the beeping sound.
When you turn on your computer, it may beep. One beep usually means everything is OK. But what if the computer has startup problems? It may make a sound (such as Morse code) to tell you something is wrong. Check the manual for your computer (or PC motherboard). If you assemble it yourself) and see what the beeping sound means. If you do not have a manual you can find it on the manufacturer's website.
If your computer is not making sound at all you are probably out of luck although some desktop computers may have a header on the motherboard where you can install cheap speakers or even a digital display with a numerical code corresponding to the error displayed as a message. But sometimes, if you don't see anything at all, it means you have a really big problem. I'm really into it. How to fix this will be in the following steps.
Disconnect unnecessary USB devices.
Before continuing, disconnect anything you don't need from your computer, such as your webcam, USB headset, external hard drive, etc. Try operating using keyboard and mouse only. (or even don't have them if you're having serious problems) to see if one of your USB devices is causing your computer to suddenly stop working.
In some cases, it may not be the device itself that has the problem; There are many computer owners who cannot access Windows if something is plugged into the front USB port, even though the ports are turned on. It will work fine as usual however, it should be empty during the boot process. The more variables you can eliminate, the better.
Reinstall the hardware inside.
There may be a possibility that the components of your computer are loose inside the case. Especially if it has been moved somewhere recently, if you are comfortable opening the computer case. You can remove the side panel and ensure the integrity of the components. It is installed correctly in the slot.
Pay special attention to components such as RAM, graphics card, motherboard cables, and heatsinks. Uninstall all of these items and then plug them back in. Make sure you click all the way. You can also try running without certain hardware, such as a graphics card or RAM. In case there is an error (and if it does not work with one stick of RAM, try using a different stick as this problem is often caused by incompatible RAM. If you have more than one stick of RAM installed, this may happen. )
Explore BIOS
Is your computer only showing the POST screen but unable to boot into Windows? Certain settings in BIOS may be causing the problem. For example, an error indicating that your computer cannot find a bootable operating system could mean that your BIOS is set to boot from the wrong drive or that your overclocking settings make your computer's screen instantly blue. You can Enter your BIOS when the POST screen appears, usually by pressing the Delete key, F2, or another key. To enter the settings
If you have customized any settings that you recently changed, try changing them again. Make sure the boot order is set to the correct hard drive, that your RAM is recognized and compatible with the motherboard, and that your CPU is not overheating (if the BIOS temperature is above 90°C, it means there is Something's definitely wrong.) Turn off the Fast Boot feature if the latest Windows update conflicts with it.
If the above methods fail. Try resetting the BIOS settings via the board using the Load Optimized Defaults option and make sure to take some pictures of the BIOS settings. So you can reset it again if it doesn't work.
Scan for viruses using Live CD
You probably have malware that is preventing your computer from booting. But with virtual environments like Hiren boot disk You can boot your computer from a CD or USB drive and scan your hard drive for malware without booting into Windows. You can download the ISO image fromThis page And follow the instructions to “burn” the image to a USB flash drive.
Restart your computer and access the boot menu, usually by pressing F11, F12, or another key assigned at startup. Select your USB drive from the boot menu and it should boot into Hiren's live environment from there. You can go to Utilities > Security (Facilities > Security) and run a virus scan with ESET and a malware scan with Malwarebytes if either program finds anything. The program will notify you and try to fix it. We hope this helps you boot into Windows again.
Boot into safe mode
If you get the Blue Screen of Death on startup it may be a bad app, a driver issue, or a specific aspect of the hardware that's causing the problem. You can try searching for stop codes that appear on the web. And see if that helps you understand the problem. However, you will likely need to boot into safe mode to fix the issue. This will be harder than it was before. But if you interrupt the boot process three times, for example by pressing the Reset button while Windows is trying to boot, you will be taken to the Automatic Repair screen. Where you can click on advanced options
Or you can create a Windows installation drive using another computer and boot directly from it. To do this, select your language and select Repair your computer when this option is available to you. Either of these methods should eventually take you to the Select Options screen. Where you can click Troubleshoot > Advanced options > Startup settings)Troubleshooting > Advanced options > Startup settings) and restart the computer. (If you don't see the Startup Settings option you may need to click Show more recovery options below.)
Your computer should have the option to boot into Safe Mode, Safe Mode with Networking, or Safe Mode with Command Prompt. You can try any of these methods, although Safe Mode is probably your best bet, or try using Safe Mode with the network you want to access the Internet. This loads Windows with only the most important drivers and services running.
If you recently installed new hardware, try uninstalling drivers from Windows via Safe Mode. If you think a new app might be the culprit, get rid of that as well. Blue Screen View This can help you go back to recent blue screens of death to see which files caused the problem. Or you can examine strings and code to detect errors.
Roll back problematic Windows updates
If you recently installed Windows Update or you think Windows might be doing so in the background without your knowledge, it can cause conflicts that make your computer unusable. It's annoying, but Windows provides the option to go back to the previous version. Even if you can't log in to Windows itself.
Go back to the Troubleshooting menu > Advanced options (Troubleshoot > Advanced options) using the instructions above. Then select Uninstall updates (Uninstall updates) Try uninstalling the latest quality or feature update, if you're lucky, this may take you back to Windows, then you can delay updating Windows until the error is resolved.
Check your hard drive for any damage.
It's possible that some data on your drive is corrupted, causing Windows to not boot properly, and fortunately, Microsoft has some tools that can try to fix the problem. Go to Troubleshooting menu > Advanced options as shown above and select Command prompt Type sfc /scannow and press Enter.
