Sort of net of both ... boot into recovery mode by holding the command and r keys down, bring up Disk Utility and repair the disk. Try to boot. If still a blank screen, reboot into recovery mode and reinstall the operating system.

Thank you, BGreg
I was able to bring up and run Disk Utility. There wasn't much to be repaired and I was happy it would be a good sign but I was wrong. I still have a blank screen.
But before I try to reinstall the operating system, I have a question. My computer was running on 10.8X which was downloaded from App Store. The only OSX I have is an older version (Leopard). Will this work or should I try to get a disk for the latest version?

You would want to download OS X 10.8 from the App Store via the recovery mode (boot with command + r keys held down). There's no disk for the latest version, as it's all available online.

Sorry for bothering you again, BGreg but unfortunately iMac is asking me to install Lion instead.
I don't know why but it doesn't show another Recovery Mode option that would let me go online and download OS X 10.8 again. And to make things worse, we recently moved to another house and now I can find all my previous disks, but Lion. I'm sure I purchased it online as I always do, but I just can't find my disk. Any other ideas you could possibly share with me?

There's no disc for Lion either; it comes via the App Store as a download, same as ML.

You may have to do this as a two step process ... install Lion, which gains you access to the App store, then you can download Mountain Lion again.

Thank you so much for your time and help! If it wasn't for you guys, I woud still be opening dozens of moving boxes just trying to find out a disk that I never had. It took a while but I got it downloaded and my computer now works just fine! Happy Holidays!
