Toshiba Laptop - blue warning then shutdown. Black screen/no fan

Hello,

A while back I dropped my laptop and the screen went black and wouldn't get past the 'Toshiba' screen with the F2 and F12 options. I reset it to an earlier date using the F2 option and it started working again as usual. However about an hour after, it went black and displayed a bright blue box with a lot of writing. The only part I was able to read was the 'shutting down to prevent further damage' before it went completely black.
I left it overnight because I thought it may have overheated.
Have tried multiple times to turn it on today however only the front lights come on (power and battery). The lights on the keyboard area flash briefly, screen is completely black and shows absolutely no sign of life. The exhaust isn't activating and it isn't making any noise what so ever. I've tried taking the battery out and restarting it etc. I've tried pressing F2 or F12 even with a black screen. Absolutely nothing works. I think I've killed it but if anyone has any ideas please let me know!! Thankyou :)
