Hey guys, Building a new PC and I've plugged in all the components but the problem is I turn on the PC and nothing comes up on screen. The fans and everything power up but nothing. I suspect it's something to do with the GPU but I'm not sure. It's an ASUS EAH 4890. Three LED lights come up on it but theres no proper manual so I cant tell what that means. any help would be much appreciated!
three red lights but i sorted the problem, turned out to be a loose cable! sorry for the silly thread but its all sorted now ta
