My BFG 8800 GT cam today however for some reason there is no signal getting through to the monitor, as me and a mate thought the fact that there is only a 4pin power lead from the PSU to plug in to the 8pin cpu power slot would be the problem (ie not enough power getting thru to the CPU) I foned up a PC repair shop and they said that a my quad core CPU will definatly require the 8 pin power lead to run properly. As the motherboard and gfx card are brand new along with the cpu culd this definatly be the problem?
