I just bought this motherboard, I have a Pentium EE 955, with 2GB DDR2, and 2GB DDR, as well as His HD 4670 AGP(1GB), an IDE HDD, and a IDE DVD+RW drive, I tried booting computer up, and I have to push power button few times, then the dvd drive light flickers sequentially, then I restarted it without dvd IDE ribbon hooked up and everything seems to boot fine, but I have no video, I tried another AGP graphics card, but I'm not quite sure where to troubleshoot from here?
