Hello!

This is my first time posting here, so thanks to all in advance for helping me out!

I just recently build a small system for a friend of mine, but I ran into some trouble when I finish building them. The system I build is the following:

AMD A64 X2 5600 2.9GHz
Jetway JM26GT4 AM2 6100-430 RT Motherboard
2G RAM
160GB Harddrive
Lite-On DVD Burner
In-Win W-Z589T Case

I know I run into some trouble while plugging in the USB drive from the case to the motherboard, since the mobo has 2 rows of pins and the case only has 1 row of plug that kind of startled me, but everything else I am 80% sure that I installed correctly. If needed, I can take a picture of the insides of the tower.

The problem arise when I try to boot the computer. When I boot up the PC, everything runs, and then I couldn't get into BIOS when I try. I've put the CD provided by mobo into the DVD rom, but it says "Cannot find boot disc! Please insert boot disc!" after it shows the first screen of how much RAM I have and system info. When I try to toss in the Windows disc it shows the same way. I couldn't get into BIOS at all, even when I press DEL from the start. I've tried plugging the keyboard into the USB port on the mobo or the USB port on the front side of the case, and still I couldn't get it to work.

Can someone please tell me what is wrong with what I did? And how can I resolve this? I really want to get this system to my friend ASAP or, if there is any parts broken, I need to return it to Newegg immediately for an exchange. Please help me out and thank you so much in advance!
