![]() 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 it. The more variables you can eliminate, the better. I’ve owned a PC that couldn’t get into Windows if something was plugged into the front USB port-once booted, the ports would work fine, but it needed to be empty during the boot process. In some circumstances, it may not even be the device itself, but the port on your computer. Try booting with just a keyboard and mouse (or even without a keyboard and mouse, if in dire straits) to see if one of your USB devices is causing a conflict. If your computer doesn’t beep at all, you might be out of luck-though some desktop PCs may have a header on the motherboard where you can install a cheap speaker, or even a digital display with a numerical code that corresponds to an error message.īefore continuing, unplug anything superfluous from your computer- webcams, external hard drives, USB headsets. If you don’t have your manual, you can probably find it on the manufacturer’s website. But if the computer is having trouble starting up, it may make a series of beeps (kind of like Morse code) that tell you what’s wrong.Ĭheck the manual for your PC (or the PC’s motherboard, if you built it yourself) and figure out what the beeps mean. When your computer boots, it may make a beeping sound-usually a single beep means everything is A-Okay. If it does, your monitor may be dead, and you need to buy a new one. If these fixes don’t help, try plugging your PC into another monitor if you have one- or even a TV-and see if Windows shows up there. I’ve had multiple people ask me for help with a computer that won’t start, only to find the brightness was turned all the way down, causing a black screen. If you’re using a laptop, this may sound silly, but make sure the brightness is turned up. If you can connect another computer to your monitor and get a picture, it may be the cable that needs replacing. ![]() You’ll also want to make sure the cable connecting your monitor to your PC hasn’t come loose, become damaged, or is at fault. Check to make sure your monitor is plugged in (again, try a wall outlet instead of a power strip), turned on, and set to the right input using the buttons on the side or bottom. If the computer sounds like it’s turning on but you don’t see anything on the screen, the computer may be booting and the monitor just isn’t showing an image. So if the troubleshooting steps in this guide fail you, it might be time to replace your power supply. A failing power supply can often cause boot problems, even if the fans and lights do turn on. 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, only some of the USB ports may actually provide power. Make sure the power switch on the back of your power supply is flipped on, and if the outlet is connected to a light switch, make sure that switch is turned on too. Unplug your computer and plug it directly into a wall outlet you know is working, rather than a power strip or battery backup that may be failing. If your computer isn’t turning on at all-no fans are running, no lights are blinking, and nothing appears on screen-you probably have a power issue. There’s nothing obviously wrong here, so why won’t the computer just start? Here are some troubleshooting steps to take. ![]() Maybe the computer doesn’t turn on at all, maybe it powers up but shuts right down, or maybe all you get is a blue screen. You sit down at your computer, push the power button just like you do every day, and…nothing happens.

If your computer won’t start, don’t panic (yet).
