Thanks for the Welcome :) Yes, I have tried the Card and on-board graphics, and nothing happens, something I perhaps should have added. When I connect the cables, it says 'D-Sub not found' or something along those lines. But when I remove the cable again, it says 'Signal lost' Would that mean that there IS actually a signal of some sort, but for some odd reason the picture is not getting through? But no, I get nothing, not a single thing, no picture, no nothing.
Since I only got my monitor yesterday, no the computer has never worked for me before, all the stuff's brand new. I will contact the firm I bought it off of tommorow since the phone lines are down on weekend's, and try and get this figured out, there's a chance I overlooked something, although I don't think I have done.
Yes, the PSU is working, LED's light up, and the fans in the graphics card spin as well.
