First of all DONT panic Your Files are OK , a piece of hardware has failed or is causing a problem but that hardware isn't usually a hard drive.
Believe it or not, the number one reason why a computer won't turn on is because it wasn't turned on!
Before starting a sometimes time consuming troubleshooting process, make sure you've turned on every power switch and power button on your computer:
• Power button/switch on the front of the computer
• Power switch on the back of the computer
• Power switch on the power strip, surge protector, or UPS (if you have one)
Verify that the power supply voltage switch is set correctly. If the input voltage for the power supply does not match the correct setting for your country, your computer may not power on at all.
If you're starting from a button on the keyboard, make sure the keyboard is connected to the computer
Check for disconnected computer power cable connections. A loose or unplugged power cable is one of the top reasons why a computer doesn't turn on.
Test your wall outlet with a multimeter or a lamp (and power strip, surge protector, etc.).
It's very likely that the power supply unit in your computer is no longer working and should be replaced. You should however test it just to be sure. There's no reason to replace a working piece of hardware when testing it is fairly easy.
Replace your power supply if it fails your testing.
In the majority of cases when a computer isn't receiving power, a nonworking power supply is to blame.
Replace your motherboard. If you're confident that your wall power, power supply, and power button are working, it's likely that there is a problem with your PC's motherboardand it should be replaced.
