Hi all. Have built various PCs. This is a first for me. Any suggestions would save my **** and would be appreciated. Here are my specs: - P4 on a D955XBK mobo, (Intel) - Antec P160 case, (sweet) - 2 GB of DDR2 RAM - Video card is a PNY, nVidia GeForce dual head 5800, (I think). - 4 Previously working IDE drives - DVD Drive - ZIP 250 - standard floppy I had to change from an AMD Athlon 3200+ to a P4 due to new video editing software, (AVID). and now this computer wont do anything after I hit the power button and the fans go and the drives spin. Any help or ideas would be greatly appreciated. All connectors are working, mobo seems fine, no viewable damage, power looks good, its a 500 watt ps. MoBo lights on board are on after power up as well as ethernet connector lights as well as fan lights. Everything seems normal expect, it just sits there. Everything sounds normal and looks normal except, it aint normal. No posts, I placed the MOBO install CD in first, the Windows XP disk as well. . . nothing. What do you guys and gals think?
