PowerPC G5 problem

hi,

i looked around in the forum, but i haven't seen a solution.

at start-up my computer would not past the white screen with the grey apple.
if i start the computer with the 'alt' key down i see my hard drive with an 'x' on it.

how can this be solved?

 

That really doesn't tell us much.

Do a start up in verbose mode by pressing Command(apple) + v.
This will allow you to see where it is hanging and once you have that information post it up here.

As of now it kinda sounds like a bad hard drive or hard partition is corrupted.

 

My vote is a bad HDD.
