I just picked up my nice new pc parts, and put them all together myself. Ive done this many times before :S AMD64 3700 San Diego Abit An8 Ultra 2x512 ram 250GB sata 6600GT Xpert Vision 256MB So I power up, and nothing. There is a led thing that displays the POST codes on the motherboard It stops on error code 04 Ive looked on google, and its something to do with the memory. So i removed the ram, and still the same thing. I removed the 6600 and hey presto it gets past 04 and then stops on the error for no graphics card like it should. So its definately the 6600. ive tried clearing cmos several times. i reseated the graphics card several times. PLEASE HELP ME!!
