Hi there, my pc wont start unless I reset the CMOS. It works well before but I unplug it for a week and when I reboot it now it has this problem. If I reboot it with the power button, it keeps on and off automatically. When I hold the power button longer, it starts but the motherboard shows d7 on it. What does that mean? Thank you in advance.

My specs:
Intel i5 3570k
Asrock Extreme 4
GTX 770
CM GX 750
Corsair Vengeance 1600 4GBx2
