I have recently built up my first PC however when I switch on the power there is no signal going through to the monitor and there is no beep everthing else switches on ie the fans, hdd etc could this be as the motherboard has an 8pin power socket for the CPU and my PSU has only a 4 pin power lead to plug in to it?? If it helps at all here is a list of the components in my PC. If it is my PSU has anybody got any suggestions for a new PSU that will supply enough power to the below setup but with another Geforce 8800GT as I will be adding a second one shortly??
Intel Core2 Quad Q6600
XFX Nvidia 680I SLI Motherboard
BFG Nvidia Geforce 8800 GT OC
Corsair XMS2 DDR2 2GB RAM
Samsung 250GB SATA HDD
Pioneer DVD-RW
LG DVD-RW DL
EZCool 550W PSU
Antec 900 Pro Gaming Case
Many Thanks
