New computeor says no signal when connected to a working monitor

[Keygan]

I'm not really sure what's going on with my new computer, but the monitor says "No Signal" when attached. I still need to install an OS if they matters, but I can't do that without being able to see anything. Any help would be appreciated. Here are the specs:

Motherboard: Gigabyte GA-M61P-S3 (Socket AM2)
Processor: AMD Athlon 64 X2 6000+ (3GHz)
RAM: 6GB PC2-6400
Video card: Sapphire ATI Radeon HD 5450
Optical drives: SATA DVD-RW and DVD-ROM
Power Supply: 500W Dynex
Case: Cougar Archon
Cooling: CoolerMaster 212 EVO with dual 120mm (push/pull) CPU fan, 3x 120mm Evercool blue LED case fans

P.S. I'm new to this site, so sorry if I am posting incorrectly


Edit: It seems as though my graphics card was bad.

Try plugging your monitor in to the on-board GPU. If that works okay, your Radeon card may be faulty or not seated properly in the slot.

Does the monitor have a button to change inputs.

my monitor only has one input

I have it connected directly to the motherboard, I will try disconnecting the graphics card to see if they helps.

Also, are there supposed to be some sort of beeping when I power on? Because I am getting no beeps.
