OK, I just built a new computer fromt he ground up. I bought a new motherboard and processor with the LGX 755 socket. I have a PIV 3.0 GHZ processor. I installed all of that like the manual says. I also bought a 512 MB DDR 400/3200 module my motherboard says that it can handle 300/400 modules. When I boot the computer up it will start i'll get to the screen where i hae the option to press DEl or whatever and than it just shuts down and when I try turn it back on it dosnt even get that far unelss i wait like a minute. Do I need to buy another DDR module, if not what is the problem. Thanks in advance for your help.
