How do I fix a computer that won't boot up?
If your computer won't boot up, there are several potential causes that you can try to diagnose and fix. Some common causes of a computer not booting up are:
- Loose or defective power cables
- Dead or defective power supply
- Overheating
- Defective hard drive
- Corrupted or missing system files
- Defective RAM
To troubleshoot, start by checking the power cables and making sure they are plugged in securely. Make sure the power supply is functioning properly by testing it with a multi-meter. Check for any signs of overheating, such as loud fan noise or hot air coming from the vents. If the hard drive is accessible, check for any signs of physical damage. If the RAM is accessible, try reseating it to ensure a good connection. If all else fails, try booting into a live CD or USB and running a system repair tool to check for any corrupted or missing system files.
If your operating system is Windows, you could try spam pressing ESC when you first power on your computer to load Windows Repair.
