Do you have 2 1GB sticks of RAM or 4 512 GB sticks for RAM? If its 4x512 try taking out 2 of the sticks and see what happens. My board (Abit AN8-SLi) is based on a similar chipset (Nforce 4) and it doesn’t like running the RAM at its rated speed with all 4 slots populated. Just a thought. Nother thought, pull all of the non-essentials out (CD/DVD drives, hard drive, floppy drive, USB stuffs, sound cards, modems, etc) and get it down to the minimum (keyboard, CPU, RAM, Motherboard, Case / Power Supply) start trouble shooting from there.
