I built my PC, after booting the first time, the bios shows and then a black screen. I reboot the PC, then press the del button to enter the bios but I cant enter the bios because I think there is a setting disabling keyboard use on boot.-up. I then go and reset the cmos, after rebooting the same problem occurs. I try putting the usb in the front usb header and the 6 back us headers and then the old ps/2 connector, still the same problem.
During the boot up, the hdd led lights up flashing and then turns off.

Specs:

i5 2400 @ 3.1ghz
msi gtx 750 1gb
gigabyte ga-z68ap-d3
zalman zm500gs 500w
12gb corsair 1600mhz
coolermaster seidon 120v water cooler

why is this happening and is there anyway of fixing it?
