iMac Stuck on Bootup

[machelp21]

Hey guys,

Here is what happened:

I updated my iTunes to iTunes 9 yesterday. When I tried to go to the iTunes store, it said I needed to update my Safari to Safari 4. When I downloaded Safari 4 and tried to install it, it said that I needed to do the software update before it would install. I did the software update and when I came back to look, my computer froze. I restarted it, which resulted in the hard drive clicking and showing a screen with a folder and question mark. Is there anyway I can fix this problem? I tried to perform a disk diagnostic test, and it said there were no problems. Please help.

Thanks

Here is what I get when I try to start it up:

I was wondering if anybody could still help me with this.

Did it freeze during the software update, or did it freeze up after the update had completed (on restart)?

Hold option as you boot to see if it detects any harddrives.

And Btw, we dont bump here.

It froze while it was updating.

Ok, I held down option while I tried to turn it on, and all that showed up was my mouse.
