Hi Guys,

I finally got the time to put together my rig and I have been having problems where I get a black screen.

This is what I'm running:

   ASRock 870 EXTREME3 AM3 AMD
   AMD Sempron 140
   2GB DDR3
   CORSAIR CMPSU-850TX 850W, 80 PLUS Certified
   2x Sapphire Radeon HD 5830 1GB XTREME

I made sure I plugged in the 2x 6-pin connectors for the video card, plugged in the 24-pin connector, and also the 8-pin connector into the motherboard.

I am trying to boot off of my USB stick and use linuxcoin.

Even without the USB, shouldn't I be able to access the bios? I am not even getting anything to show up on the screen. My cpu and video card's fans are spinning, but nothing is showing up on the screen... I am using just a basic dvi monitor. I tried to only use one video card to see if one was broken, but it still didn't work.

Some extra questions I had also:
When I built a computer in the past, when I stick the my video card into the PCI-E slot I hear a click, but on this motherboard I don't so I'm unsure if I put it in all the way (it's easy to move around in the slot/not very sturdy).
