Hey all ive just built a new Intel Duo System, my first dual core system ive built, but the fourth intel system. I plonked the CPU in the socket, plugged in everything that needs to be plugged in, including the switchboard on the PCI-E which is on normal mode, but when i power on there is no display on the monitor, now ive replaced the 7900gtx with my brothers older 6600 GT and still the same problem. So if its not the graphics card what the hell is going on? I have only a few strands of hair left, need help before i become bald!
Until we get those specs, I can only guess at the problem, but I would say at first glance that your motherboard is the issue here. Without a bit more detail on the problem I can't really say for sure though.
