Stuck With 500 Internal Server Error

[codename25]

Hi,

My website is showing 500 Internal Server Error instead of my web page. It is so strange to see this and i am sure it is not a regular error message that i can find while i'm coding. For 1 hour and now my website is still showing the same 500 Internal Server Error and when i checked my error log it showed like this

[Tue Sep 23 09:15:59 2014] [error] [client 208.122.6.102] File does not exist: /home1/..........

I have no idea where to start to fix this error. My codes were fine and it was working fine until today. Anybody here have some idea how to fix this. Please help me.
