Everything appears to be installed as it should be. The green light comes on. I've tried buffalo technology (winbond5) pc3700 as well as micron pc 2700 which are both supported. Still no video. I've tried clearing cmos/reseating cpu/hsf/ different video cards that i've tested in other machines and know to be working. Another thing thats odd is it doesn't beep at all, even when there is no ram in it. The speaker is hooked up. Seems to not beep at all regardless of anything. Any ideas? Should I just RMA it? I know the ram is good as well as the video cards. The only slot being used is for the video card. I've got a pair of raptors/cd burner/and a pair of 120gb wd se's hooked up. Its an antec case with an antec 430 watt true ps. The processor is a 2.6c retail that I just took out of the box.
