White Screen with a question mark folder....

[marmaladeskies]

One day when i was working no my mac it just suddenly froze i tried Command-Alt- Delete but that wasnt working either so i force shut it down. When I tried to start it up again the white screen with a question mark folder... appeared.

I searched about it online and tried using:

Disk Utility with the installation disk
The only thing I could click on was "verify Disk Permission" and when i did I got the message "Verify permission for "Mac OS X Install Disc 1" Error: No valid packages Permission verification complete and I really dont know what to do from there

Then I tried using it in Safe Mode that didnt work out
and now im trying fsck though I dont really know how to use it i only typed in "/sbin/fsck -fy" but I dont know how to solve the problem from there.

Did anyone of you guys have this problem?!
Please help me asap !!!!

Seems like your hard drive failed. Or the OS got corrupted. Or kernel panic. But to solve the problem... iono.. sorry.

When I was trying to do everything i did already once again when i went into safe mode I got the message kernel panic
