Laptop won't boot after booted with F5

Hello,

I am having issues and I need help. I rebooted my laptop while holding the F5 and now it won't start nor show anything. all this happened when I was trying to put an image on my compaq R3000 notebook which gave me the error 25002. so when I did a reboot while holding F5 the computer went off and I can hear the fan going on but nothing showing on monitor. please help.

thanks,
Maestro
