Bios doesn't see hard drive and cd-rom

I've spent several days trying to repair my hp pavillion desktop ruing Windows 7. Through some boot USB applications it now can see the the USB drives but I caot run the windows restore disks on a cd rom which tries to spin but never upto full speed. I have also copied the contents onto a stick but it will only go until it's looking for a path and there's no drive to goto. I was able to us a sata cable and power supply to transfer my all my files off HD so I'm OK with a complete wipe but I caot get there. How do I start over so it recognizes the hard drive and cd rom again? FYI checked all cables and memory card coections. Is my mobo hosed?
