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?

Have you tried with another graphics card?

The only other graphics card I have is an ATI Radeon X1950 Pro (I did however try it anyway even though its an Nvidia chipset on the mobo) and the same thing happened no signal goin through to the monitor

Ah rite, well that way you can't really guarantee that a new psu will solve your problem then. There is a good chance though...

I do hope so, my Xbox360 died last week and I cant play my ps3 at the min so ive been feelin like pullin my hair out!!!!

Did it work before you put the 8800GT in?
