I just put together my new build today and it will not boot. Power is running through everything (case, PSU, video card, CPU fan) but there are no sounds for boot and no video output. The first boot I tried worked with a CD boot option screen, at which point i shut off power to make more adjustments (cable management and partial case reassembly). Since then I have tried booting and not gotten any video output.

Intel i5 IB
ASRock Extreme Z77
Corsair 4gb x 2
Crucial SSD 64gb
Asus OEM DVDRW
Asus Radeon HD 7870
Asus widescreen monitor with VGA through motherboard for boot

CPU power supply is connected (I checked, plus it booted once already)

Should I reset the BIOS or is this possibly related to something else?

Thanks ahead of time.
