Ok, I switched on the computer, and it comes on, but the monitor is getting no picture whatsoever, and the LED lights on the front of the case are not lighting up (don't really know if they should yet, or not)
I've got two video cards installed (SLI), so I'm not quite sure how to correctly hook such a thing up. I'm connecting the cards directly from the PSU (there are plenty of connectors). The documentation was less that stellar.
