Fixing a computer that won’t turn on can be a relatively simple process or an incredibly complex one, depending on the underlying cause of the issue. This guide will provide a basic overview of the steps to take when you encounter a computer that won’t turn on.
Step 1: Test the Power Supply
The most common cause of a computer that won’t turn on is a malfunctioning power supply. If the power supply is faulty, it could prevent the computer from receiving any power at all, meaning your computer won’t turn on. The first step to take is to test the power supply itself. To do this, unplug the power cord from the wall, and then plug it back in. Also check the power switch on the power supply (if it has one) by flipping it off and on several times. If the power supply is still not working, consider replacing it.
Step 2: Check the Connections
Check all the connections between the power supply and the motherboard and other components. Make sure that the cables are all properly plugged in and that they are securely fastened. If the cables are not connected properly, then the computer won’t receive any power.
Step 3: Try to Reset the BIOS
If the power supply and connections are all functioning properly, then the problem may be with the BIOS settings. Try resetting the BIOS by removing the CMOS battery. This will reset the BIOS to its default settings, which should fix any issues with the BIOS causing the computer not to turn on.
Step 4: Inspect the Motherboard
If the computer still won’t turn on despite resetting the BIOS, then there may be an issue with the motherboard. Carefully inspect the motherboard for any signs of physical damage, such as burns or melted plastic. If you find any evidence of physical damage, then replace the motherboard.
Step 5: Try to Boot from a Bootable Device
If all the above attempts to get the computer to turn on have failed, then try booting the computer from a bootable device. For example, insert a bootable USB drive containing your operating system into the USB port, then turn on the computer. If the computer boots up normally, then the problem is likely related to the hard drive or operating system.
Step 6: Replace the Hard Drive or Operating System
If the computer boots up from a bootable device, then the hard drive or operating system may be damaged. Try to back up your important data from the drive before replacing it, or reinstall your operating system onto the same drive. If this does not work, then you may need to replace the hard drive or buy a new operating system.
Step 7: Have it Checked by a Professional
If none of the above steps have been successful, then it may be time to consult a professional. A professional technician should be able to more accurately diagnose the issue and replace any components that are required to get the computer running again.
In conclusion, fixing a computer that won’t turn on can be a fairly straightforward process, but in some cases it can be much more complicated. If the computer still won’t turn on after attempting the above steps, then it may be necessary to have it checked by a professional.
