Hello

Can anyone help me with a problem i'm having with my Dell Dimension 5100 desktop? Yesterday my light blink in my house and my computer went out when i try to reboot it, it gave me a error code: 0F00:136C and a message saying Msg: IDE device failed: Blank media or no media is present in optical drive. Test requires media with digital data (resource CD, Installation CD)  The given error code and message can be used by Dell Technical support to help diagnose the problem. Does anyone know what this means and how to fix my computer? Also little more down in the meddle of the page there was one more error message saying:  "unmoutable boot volume" Please help me if anyone has any idea what this mite be and why my computer is not working now?

Thanks

Alana
