i've built my first computer and im still waiting on the hard drive, what i want to know is should the computer display the blue screen and make the beep without the hard drive?
 
Solution
Are there any drives in there now? If you boot without a HDD attached you should see the BIOS logo flash, then a message to the effect of "Operating System not found" or "Reboot and select proper boot device" or something like it
