Ok so I fixed the problem. I was reading another forum with a similar issue, where the monitors had the 'no connection' message, and 5 beeps for a Gigabyte mobo. And they found out that it was a cord problem. So I gave it a try since nothing else seemed to be working, and after I swapped out the cord, I turned on my computer and it worked!
If anyone else has a similar problem to this, I would try to see if it is a cord problem first, before taking your computer apart.
