(Analogy: M-SUR/Shutterstock)

You sit down down at your computer, push button the power button only like you exercise every day, and...nothing happens. Mayhap the computer doesn't turn on at all, maybe it powers up simply shuts correct down, or perchance all you get is a blue screen. There's nothing manifestly wrong here, so why won't the computer just get-go? Hither are some troubleshooting steps to take.

Requite It More Power

If your computer isn't turning on at all—no fans are running, no lights are blinking, and naught appears on screen—yous probably take a ability issue.

Unplug your calculator and plug it direct into a wall outlet you know is working, rather than a power strip or battery backup that may be failing. Make certain the power switch on the back of your ability supply is flipped on, and if the outlet is connected to a light switch, make sure that switch is turned on too.

If you're using a laptop, make sure your charger is plugged in properly and to the correct port—if it charges via USB-C, simply some of the USB ports may actually provide power. A declining power supply can oft cause boot problems, fifty-fifty if the fans and lights do plough on. And then if the troubleshooting steps in this guide fail yous, it might be time to replace your ability supply.

Check Your Monitor

If the calculator sounds similar it's turning on but you don't encounter anything on the screen, the computer may be booting and the monitor just isn't showing an image. Check to make certain your monitor is plugged in (again, try a wall outlet instead of a ability strip), turned on, and fix to the right input using the buttons on the side or bottom.

You'll also desire to brand sure the cable connecting your monitor to your PC hasn't come loose, become damaged, or is at fault. If you can connect another computer to your monitor and become a picture, it may be the cable that needs replacing.

If yous're using a laptop, this may audio dizzy, but make sure the brightness is turned up. I've had multiple people ask me for help with a computer that won't get-go, merely to find the effulgence was turned all the way down, causing a black screen.

If these fixes don't help, endeavour plugging your PC into another monitor if y'all have i—or even a Goggle box—and see if Windows shows up there. If it does, your monitor may exist dead, and you lot demand to buy a new 1.

Mind for the Beep

When your computer boots, information technology may make a beeping sound—usually a single beep ways everything is A-Okay. But if the calculator is having trouble starting up, it may make a series of beeps (kind of like Morse lawmaking) that tell you what's wrong.

Check the manual for your PC (or the PC's motherboard, if you built it yourself) and effigy out what the beeps hateful. If you don't accept your manual, yous can probably find it on the manufacturer's website.

If your computer doesn't beep at all, you lot might be out of luck—though some desktop PCs may have a header on the motherboard where yous can install a inexpensive speaker, or even a digital display with a numerical code that corresponds to an error message.

Unplug Unnecessary USB Devices

Earlier standing, unplug anything superfluous from your figurer—webcams, external difficult drives, USB headsets. Try booting with just a keyboard and mouse (or even without a keyboard and mouse, if in dire straits) to encounter if one of your USB devices is causing a conflict.

In some circumstances, it may not fifty-fifty be the device itself, but the port on your reckoner. I've owned a PC that couldn't get into Windows if something was plugged into the front end USB port—once booted, the ports would work fine, but it needed to be empty during the kick process. The more than variables you can eliminate, the improve.

Reseat the Hardware Inside

There's a chance a component of your computer has come loose inside the case, especially if it was recently transported somewhere or if you were working inside of information technology.

If you're comfortable opening your computer upward, remove the side panel and make sure the components are properly seated in their respective sockets. That includes your RAM, graphics bill of fare, motherboard cables, and the CPU heatsink. Remove them completely, then plug them dorsum in, ensuring they click in all the fashion.

You might as well try bootingwithout certain hardware, like the graphics carte or ane of the RAM sticks, in instance they're faulty. (And if it doesn't work with ane RAM stick, try the other.)

Explore the BIOS

If your reckoner turns on and you lot encounter the Post screen merely can't boot into Windows, certain settings may be causing a problem. For example, an error stating that your reckoner tin can't find a bootable operating system may mean your BIOS is prepare to kick from the wrong drive or your overclocking settings are causing the computer to bluish screen immediately.

Enter your BIOS when the POST screen appears, usually past pressing Delete, F2, or some other key to enter setup. If you've tweaked any of these settings recently, try irresolute them dorsum.

Make sure your Boot Order is ready to the correct hard drive, your RAM is recognized, and that your CPU isn't overheating (if information technology's to a higher place xc degrees Celsius in the BIOS, something is definitely wrong). You might also turn off the Fast Boot characteristic, in case a recent Windows Update is conflicting with information technology.

If all else fails, endeavor resetting your BIOS settings beyond the board using the Load Optimized Defaults option. Merely be sure to snap a few photos of your BIOS settings so you can set up them back if that doesn't work.

Browse for Viruses Using a Live CD

Information technology'south possible you have some nasty malware that's preventing your computer from booting. Simply with a live environment like Hiren'southward Kicking CD, yous can boot your computer from a CD or USB drive and scan your difficult bulldoze for malware without booting into Windows.

Download the ISO image from this page, and follow the instructions to "burn down" it to a USB flash drive. Reboot your computer and access the Boot menu—usually by pressing F11, F12, or another primal defined at startup. Choose your USB drive from the boot menu, and it should boot into Hiren'south alive environment.

From there, you can head intoUtilities > Security and run a virus scan with ESET and a malware scan with Malwarebytes. If either program finds anything, information technology'll let you know and effort to fix it, which volition hopefully let y'all to boot into Windows once once again.

Kicking Into Safe Mode

If you're getting the Blue Screen of Death at startup, information technology could exist a result of a bad application, driver issue, or other hardware quirk causing problems on kicking. If you can, Google the stop code that appears and see if information technology gives you any insight into what's wrong.

Chances are, though, y'all'll have to kicking into Safe Mode to fix the trouble. This used to be an like shooting fish in a barrel process in Windows seven, considering all you had to do was printing F8 as you booted up. It is much trickier in Windows ten, but ordinarily if you lot interrupt the kicking process 3 times—say, by pressing the reset button as Windows tries to kick—it'll take you to the Automated Repair screen, where you tin can click Advanced Options.

Alternatively, you can create a Windows installation bulldoze using another PC and boot from that directly, choosing your language and selecting Repair Your Reckoner when given the option. Either of these methods should eventually get yous to the Choose an Choice screen, where you lot can clickTroubleshoot > Advanced Options > Startup Settings and reboot the computer. (If yous don't run into the Startup Settings option, you may need to click Come across More Recovery Options along the bottom.)

Your calculator should then give you the option to boot into Safety Mode, Safety Manner with Networking, or Safe Way with Command Prompt. Y'all can try any of these, though the most minimal Rubber Way is probably your best bet, unless yous need to access the net (in which example, choose Safety Mode with Networking). This volition load Windows with simply the most crucial drivers and services running.

If you installed any new hardware recently, try uninstalling its drivers from Safe Mode. If you lot call back a new application might be to blame, become rid of that too. BlueScreenView can help you look back through your most recent Blue Screens of Death to see the file that acquired the problem, or any issues check strings and codes to Google.

You might fifty-fifty try running System Restore to try and get your PC back to the last known working configuration. Reboot the PC normally to encounter if it fixed the trouble. If non, y'all can enter Safe Mode once again, or try moving on to one of the side by side troubleshooting steps in this guide.

Curl Dorsum a Problematic Windows Update

If you recently installed a Windows Update—or you lot think Windows may have done and then in the groundwork without you realizing—it may have caused a conflict that rendered your computer inoperable. Information technology's annoying, but thankfully, Windows does offer the choice to coil dorsum to the previous version, fifty-fifty if you lot can't get into Windows itself.

Head back to theTroubleshoot > Advanced Options menu using the instructions above, then choose Uninstall Updates. Try uninstalling the latest Quality Update, or—if you recently tried to upgrade to a new major version of Windows 10—uninstall the latest Feature Update. If you're lucky, this may get you dorsum into Windows, at which point yous can delay Windows updates until the kinks are worked out.

Cheque Your Hard Drive for Corruption

It's possible some data on the drive is decadent, preventing Windows from booting properly. Thankfully, Microsoft has a few tools that tin can attempt to fix the problem.

Caput to theTroubleshoot > Advanced Options bill of fare as described in a higher place and choose the Command Prompt. Typesfc /scannow and press Enter. Windows volition check your drive for abuse and attempt to repair any problems.

Y'all can also try thechkdsk C: /r command, which will exercise a broader search for file corruption and bad sectors. (If you lot have multiple drives, you lot may want to runwmic logicaldisk go volumename,name and replace the drive letter of the alphabet with the correct one from the resulting list.)

Repair a Busted Bootloader

Sometimes your Windows installation is fine, but the bootloader—the information that governs Windows' boot process—is corrupted. This often happens if you lot clone your difficult drive improperly, in which instance you lot tin can try the cloning procedure once again, making sure to clone theentire bulldoze, non just the segmentation where Windows resides.

It can also happen if you try to dual-boot Linux or create new drive partitions and mess something up along the manner. You lot'll often get a bulletin saying "Error loading operating arrangement," "Invalid sectionalization tabular array," or "FATA: No bootable medium found! System halted."

If you lot have a good backup, yous tin try to repair the bootloader using Windows' built-in tools past going toTroubleshoot > Advanced Options as described above, so choosing Startup Repair. I wouldn't attempt these steps unless y'all have your files backed up, as messing with partitions tin ever risk the loss of information. Yous tin can likewise run the Command Prompt from this menu and endeavor running one of the following commands:

bootrec /fixmbr
          bootrec /fixboot
          bootrec /rebuildbcd

If that doesn't work, repairing your bootloader may be more complicated due to newer EFI bootloaders—you can see instructions on doing so here—but it may be easier and faster to reinstall Windows from scratch and restore from your backup.

Test the Bulldoze in Another PC and Pray

If all else fails and you don't take a backup, take your hard drive out of your computer, connect it to a USB adapter, dock, or enclosure, and plug it into another known working PC. (Or, if you don't have another PC, try booting from a Linux Live CD on your electric current machine.)

As long equally the drive is still working—a big "if"—y'all'll at least be able to copy your files onto an external bulldoze for safekeeping earlier you reinstall Windows or send the PC in for repairs.
