Hi everyone, I got a new mobo and cpu yesterday and after installing all the parts I put my old hdd in, after the pc boots I got an error; no hard disk detected. i know the hdd is fine because i put it back in my old build and it booted fine, i know when installing a new mobo you should format which ive been trying to do but when i reach the window where you choose the language theres no mouse or keyboard working, and i know the mouse and keyboard is fine because i used both in the boot menu. my current specs are p8z68-v asus intel i5 2500k nvidia 560ti asus corsair 850watts 8gb ram 500gb hdd ps; sorry for poor grammar and spelling mistakes but was forced to write this on my phone. Also, i looked in my bios and it clearly names both my hdd and blu ray drive.

First, try the basics. Take out the 560 and just install the RAM, CPU, HDD and PSU and see if you can get to BIOS.
