Ok, I just built this computer. I installed RAM chips one at a time. I have K9N SLI platinum board, AMD 64X2 5400 CPU, 4 GB (only 3 installed) Crucial Ballistix pC6400 RAM (4 x 1 GB), 2 GeForce 7600GS 512mb graphics cards in SLI, and am running Windows Vista. The system works fine on with 1,2, or 3 chips installed, but whenever I put the 4th chip in I get nothing. I thought maybe it was just that chip, but I traded it with another and it worked fine. With all 4 installed, the system turns on, but no video is displayed, the lights are just solid green on the case, and nothing happens. The NUMLOCK on the keyboard turns on also. CTRL ALT DEL doesnt work, and when you hit the power button on the case nothing happens, also the reset button seems to work, but not always. The only way to power the system down it seems is by shutting off the PS. Any ideas on why this is happening and how to fix it would be greatly appreciated! Thank you!
