You should be hearing a post beep of some sort. Disconnect everything except cpu, ram, front panel connections and psu to see if we can get it to post and get into bios. After that we will add back cd, hd, usb and other peripheries you may have.
I have the exact same problem (no beep when I power on) and I have done a barebones test and still no beep.
By that I mean I disconnected everything but RAM, MB, Processor, PS, Monitor and Keyboard, and still no beep.
The MB is Asus P5N73-AM
processor - Intel Pentium DC E5200 2.5GHz.
I assembled it myself. Please help, I'm at my wits end.
