I have an acer aspire 5315 and i dropped my LAPTOP on the floor with it turned off. Then once I restarted the pc it didn't display ANYTHING and after about 5 to 10 seconds it shutoff please help. I am not sure which hardware it is the fan was loose but i already screwed it back in.Remove and re-seat both the HDD and your CDROM drive...
Do this with the BATTERY removed and all power disconnected.ok i installed the hdd but i cannot seem to get the dvd drive out :S btw it is still having the problem Try reseating the CPU and memory. By the sounds of it the POST is failing.

Can you try linking up to external monitor to see if you can get any more info?

Are you getting any audible bleeps?

ok i'll do that but no there is not any audios it just doesen't display anything and turns off i have no tried the cpu thing yet but i will make sure to do it.You dropped it. Who knows what broke? Hard drive, other components? If I were you I'd take it to a shop or send it to the manufacturer for evaluation and repair.Ok if that is the CASE it really doesen't matter because i have plenty more computer .Fine.
