Alright I'm not having the computer issue but my girlfriend is and I figured I'd come here and ask if anyone has any ideas

Computer:
HP Pavilion n6224a

the other night she turned off her computer and went to bed, woke up the next day to turn on her computer and nothing happened. Fans were running, hard drive works, but nothing shows up on the monitor. With my own testing the monitor and the hard drive are fine. But when we start the computer nothing loads, no bios no nothing. Is this a motherboard issue (I'm hoping its not)? We're not getting the hp symbol, no blue screen just black.


Any ideas and help would be great, thanks.
