Black screen and it says no input goes into sleep

[harleygirl]

Hello, My computer has a black screen.. it says no input and goes to sleep.. the fans are constantly running.. I've seen posts about things to do but I can't access the computer at all..

If you are getting the no input message on the screen then your not getting a signal from the video card. There is no way to know if your computer is even getting to the post unless you are hearing the post beep. The fans are running so that means that the power supply is good but it doesn't mean that the motherboard is or the video card. Are any of the leds lighting up on the motherboard ?
