I got this old computer, dont know how old, but after not using it since I got my laptop 2 years ago, I had tried to turn it on as it has a lot of storage plus whats stored. It was sitting under the desk, there was a compartment that can house it, and so I plugged in the power supply or cord into it and pressed the power button. Nothing happened except the power light would blink orange. So I tried to unplug it, wait and plug it back in to try again with no luck. I am using that same power cord for the monitor as it has the same connection and it works fine. I want to try and fix it and avoid any technician, though we have a tech in mind whos a good person that has fixed it before, at one point replaced it.
Anyways, facts:
It is a dell Windows XP desktop
When I press the power button, it blinks orange light, even for a few seconds after i unplug it
nothing turns on in the back, fan, lights ect
