How to Diagnose a Computer That Won’t Start

When Windows won’t start, it might be a few different things. Windows won’t start or the Power On Self Test (POST) is still running. This is a fine line between a hard disk failure and a software issue. In this guide, we’ll go over ways to diagnose a computer that won’t start. Read on to learn more about the Blue Screen of Death and its various causes. If any of these sound familiar to you, try the troubleshooting steps outlined below.

Static electricity

If your computer will not start, it could be due to static electricity. Static electricity is a buildup of an electrostatic charge on a surface. For example, if you’re wearing socks and walk across a carpet, your feet create an electrostatic charge when they touch another object. This charge transfers to the other object, causing it to receive a slight electric shock. If this happens frequently, your computer may be in danger of static electricity and need repair.

If you suspect static electricity as the cause of your computer not starting, you can try to clean out the area around the key. This is especially helpful if you have grit and dust in this area. Otherwise, you may need to take your laptop to a repair shop for repairs or talk to the manufacturer to make sure it’s covered by warranty. If your computer still won’t start, it may be due to a faulty internal component.

To prevent static electricity from damaging your computer, you should first ensure that you are grounded. You can do this by avoiding standing on carpets. Hard surfaces conduct electricity more efficiently. Avoid moving around a lot, since movement creates friction, which is a major cause of static electricity. Avoid wearing clothes that are static-sensitive. Those clothes should also be grounded. You don’t want to get shocked by static electricity.

Another way to detect static electricity is to measure its voltage. Static electricity can damage your computer if it is exposed to over 1,500 volts. The danger comes when the electricity reaches five to ten times higher than that. Nevertheless, static electricity is harmless if you don’t feel any electricity. Besides, you should always disconnect your AC adapter or battery if you are working on the computer’s internal components.


If your computer will not start, the problem may be on the motherboard. It may be plugged in incorrectly or is loosely connected to the power switch. You can check the power switch pins with your motherboard’s user guide. If it is not connected correctly, the power switch may be damaged or malfunctioning. In that case, you may need to replace the motherboard or CPU. To troubleshoot the problem, try one of the following steps.

If the power switch or a power button on the case is not functioning, the problem may lie with the motherboard. Check the power switch headers. Check the case power switch. If it is functioning correctly, you should be able to start your computer. If the problem persists, it may be the power supply. If you don’t see any light or fans on the power switch, try re-seating the motherboard.

Another cause for a computer not to start is a malfunctioning motherboard. It may not be as obvious as a CPU, but a motherboard can be just as faulty. Using a spare or a computer store’s tech support may help. To determine whether the problem is on the motherboard, you can also use Windows System Restore to restore the system to a point before the new application was installed. Viruses and malware are known culprits for causing a motherboard to malfunction. A virus or malware infection can corrupt the system, so make sure to scan the drive, the operating system files and any recently downloaded files.

Changing the RAM or CPU may also be necessary. Memory is finicky. While this is a common problem, it is also possible to install a new CPU or other hardware without damaging it. If the new hardware doesn’t work, you may need to install a new BIOS or UEFI version. Hopefully this will resolve the issue and prevent it from recurring. If you’re unsure about the process, you can ask an expert or try one of the above methods.

Beep codes

If your computer will not start, you might be able to pinpoint the cause by reading the beep codes. You can usually find them in the motherboard documentation or on the computer itself. These beeps are designed as failsafes that are meant to alert you to a potential hardware problem. However, if you don’t have access to any documentation, you can look online for the manufacturer’s manual.

The manufacturer of the BIOS chip is the most likely cause of a beep code. Many computers come with a generic bios chip, but there are different brands and versions. Typically, an AMI beep means that the graphics card is not installed. A three-beep sequence indicates insufficient memory. Three short beeps indicate a memory issue. Two beeps, on the other hand, mean that the processor or memory is faulty.

Successful computers will emit one beep during startup, and will continue the process without issue. However, computers that have trouble with startup will produce beep codes, which are a form of error message. Many times, these problems are caused by a simple mistake, such as not connecting a hard drive or cable. Another possible reason for a beep code is when there are several hardware problems. There are different beep codes for different kinds of hardware, and each of them can mean a different type of error.

If no beeps are produced, it’s important to check the motherboard and CPU. They may be malfunctioning. The CPU could be defective, or the CPU may have been disconnected. If this is the case, you can try putting fresh thermal compound between the CPU and the heat sink. If those methods are unsuccessful, you should try replacing the PSU and try your computer again. You may also try identifying the beep code, which will allow you to identify the cause of the computer’s malfunction.

Onboard power button

If your computer won’t start, it’s most likely due to a problem with your onboard power button. Luckily, not all motherboards have the same onboard power button. Simply check your motherboard’s manual to see which power button is located on your motherboard. If your computer won’t power up, you can use a screwdriver to connect the reset button to the pins on the motherboard. This will let your system boot up, but it won’t produce the click that you’re looking for. If you short the pins on the motherboard, you’re likely to cause a faulty connection. If you see any sparks, you should immediately take your system to the computer repair shop.

Another cause of a faulty power switch is a bad case or motherboard. In case of a desktop, the power button is located on the front of the computer’s case. You may need to use a reset button to turn your PC on. Some motherboards have tiny power buttons integrated into the board. To test the power button, connect the wires with a screwdriver. Then, plug in the power switch cable to the main power cord. If all the connections are good, your PC should boot. If the problem persists, take your computer to a repair shop.

Booting in’safe mode’

When your computer won’t start, one of the first things you should try is booting up in’safe mode’. This mode is designed to help diagnose problems and repair the most common ones, but it is not something you should do everyday. While your PC might start in safe mode, it will be loaded with bare minimum drivers and software, so you can pinpoint the exact problem more easily. Safe mode can cause problems, however, and you may experience problems with your screen resolution, applications, or computer’s performance. But, these are all normal effects of missing drivers and software, so it’s best to try this mode once you’ve encountered a problem with your computer.

The first option that will give you the option to boot in’safe mode’ is to choose ‘Advanced’ on the Startup Settings screen. Choose ‘Advanced’ and ‘Restart’ to see what options are available. Using the advanced option will allow you to select whether or not you want to boot into Safe Mode with Internet access. The easiest way to exit’safe mode’ is to restart your PC. You can do this by holding down the power button until your PC restarts.

Alternatively, you can boot into’safe mode’ by pressing the Windows key + R at the same time. Alternatively, you can also select the’safe boot’ option in msconfig. The recovery environment is called ‘Safe Mode’ and it allows you to do things in’safe mode’. Once in’safe mode’, your computer will usually start up much quicker than if you hadn’t done this.
