black sceen

[jsf3157]

• black screen on startup
• power button light on
• caps lock blinks white light with an interval of 3 seconds
• the Wifi light being orange
• the one beside the wifi with a globe sumbol  being white throughout
• the charging light turns white for a split second when I insert the AC cord but then shows blinking orange throughout
• A light just beside the card slot next to audio jack is orange throughout

The fan runs around 6-7 seconds after I start and as soon as the fan starts the caps lock light stops blinking.

I tried removing and re-seating the memory modules with every combination but, nothing worked.

I have two modules both of 4 GB each.

Can you please help ?
