I just built a i7 930, DX58SO MB, Kingston 1066 DDR3 RAM, WD 500 MB HD and PNY GeForce GT220 DDR2 1GB video card. With all RAM sticks installed, there is no boot, just lights and fans. With RAM in Channel B&C, the computer boots to the OS. I've tried installing RAM one stick at a time and various configuratins, but the only one that works is B&C. I need 8 GB, but only getting 4 GB. Please help!
