Problems with a new motherboard?

I just recently purchased various new parts to build my own computer and am having a bit of trouble. I've plugged everything in, and everything boots up, except there is no video output. Now I've tried using an old but reliable Vgc i had lying around from another computer, but still no video output. Now people have been telling me that the problem is, im takinga hdd from an another comp that works with XP as the OS and that it wont transfer over to accept the new mobo. The new motherboard is an ASUS M4A87TD EVO AM3 AMD 870 SATA 6Gb/s USB 3.0 ATX AMD Motherboard from Newegg.com So my question is what should I do?
