Computer Won't boot, Screen is blank

HP Recommended
HP pro 3520 Business Pc
Microsoft Windows 7 (32-bit)


Hi there!
I have a Hp pro 3520 Business Computer Running windows 7, over 2years now it hasn't come on.

Whenever i try to boot it, the light in the power button comes on but the screen remains blank with nothing happening.

I have tried troubleshooting the computer using all the steps i could find on the HP website but all to no avail, the screen is still blank.

How do i Go about fixing it please?
