Desktop Stuck At ASUS Motherboard Startup Screen

I have an ASUS P5N73-Am Motherboard with an Intel Dual Core Processor and 4gb of RAM running Windows 7. I shut down my PC last night because I noticed a buzzing noise which sounded like one of the cables rubbing against the case fan. When I booted up my tower in the morning it got stuck at the asus mobo screen and wont even let me hit delete to see bios options. I removed each stick of ram and tried rebooting and received the same thing. When i removed both sticks and booted up the screen was black and the motherboard kept beeping. I unplugged each hard drive and tried booting up and got the same result. My 4th hard drive which was the last, my system seemed to get to a different screen which said something like windows detected a hardware change and that I needed a CD or something like that. I am pretty sure that must have been the drive with windows installed on it.

Any help is appreciated? I'm not sure if the mobo is finished or if its something else.

Thanks,

Joe

Have you tried just clearing the cmos via the jumper? I would try that and look at the ram again.
