Monitor problems (building a new pc)

[Jeffdabomb]

Hello, I am new to Tom's hardware, and I hope that toms hardware can help me with my problem.

For the past couple of days I have been building a computer from parts my uncle gave me as well as some I had gotten from the internet. My uncle supplied the motherboard, processor, mouse and keyboard, while I supplied everything else.

For explanation reasons, my motherboard is this (http://www.newegg.com/Product/Product.aspx?Item=N82E16813135233&Tpk=A780GM-m3)
While my processor is an AMD Athlon II X2 250 processor (3.0 Ghz)

Anyway, I have been experiencing trouble with getting the monitor to respond to the computer. At first I thought it was the video card I purchased (radeon 5770), I then decided to take it out and try to use the on board video card on the motherboard, but the screen continues to get no signal. I then thought it was the actual screen so I tested it on another monitor and it still doesn't work!

For the record, my power supply is more than capable of running this machine (http://www.newegg.com/Product/Product.aspx?Item=N82E16817182039&Tpk=rosewill%20600%20watt), I made sure I plugged in the necessary parts of the motherboard that needs energy correctly. I also made sure that my sata HDD and SATA DVD-Rom disk are powered up and connected to the motherboard via a SATA Cable.

Even after taking all the precautions, the monitor does not receive a signal from the motherboard. My computer case also doesn't beep, even though I am fairly sure I plugged in the necessary front cables correctly My computer case is http://www.newegg.com/Product/Product.aspx?Item=N82E16811147023.

If someone could please help me please! I have been experiencing this problem for too long and I would really want my PC up and running soon!

According to the specs on your motherboard you can use a VGA cable or DVI. You may have a bad VGA or DVI cable whichever you are using. Also your Radeon 5770 should only support HDMI or DVI. Check your cables with new ones and setup your card in the bios rather than using onboard graphics as I am sure you are aware. Sounds like a bad cable since neither the radeon card nor the onboard video works and you said you tested it on another monitor. I doubt both the onboard graphics and the radeon card are bad.
