I turned on my computer but it wouldn't send signal to the monitor. Please help!

I turned on my Compaq Presario CQ5110Y Desktop PC but it wouldn't send signal to the monitor. I opened up the side but everything looked like it should be working perfectly! All the lights were on and the fans were running. My USB mouse and keyboard weren't working either. When I unplugged my mouse and plugged it back in the light on the bottom quickly blinked and turned off again. The keyboard wouldn't work at all. 

I'm at a loss. Hopefully someone will know what's going on!

Hi

 

A failed power supply

A faulty motherboard

A failed monitor

CPU dead

Graphics failure.

Memory fault.

DEAD HDD

 

Do you have a Diagnostic option when powering on ESC and F2 or something?

 

fans running suggest RAM and MOBO could be fine, also power supply.

 

If in doubt please ask.
