Dv6 black screen and flashing caps lock. Help please!!!

HP Envy Dv6 7229wm
Microsoft Windows 8.1 (64-bit)

I have a HP Envy Dv6. It was having problems overheating so i opened it up to clean the fan and air intake. I put it all back together and now I have a black screen. I can hear the hard drive spin but the fan only comes on sometimes. If i blow in the intake when the fans not running it starts to spin. The caps lock led is flashing constanly at a rate of 1 second, no pause, just 1 second intervals. Did i kill the fan or is the flashing telling something else. Any help is appreciated. Thanks

Thank you for your response.

 

I have checked and rechecked all cables and anything else that could have come undone. Still not booting up. Do u have any idea what the caps lock led blinking means? Its blinking at a rate of one blink per second.

 

Thanks
