Assembled my second computer after reading "The best pc for the money" in the 10\03 issue of pcmagazine, following the author's list of components except for increasing the hard drive size. seagate 320 sata drive Lite-on SHM-165h6s dvd3rw OCZ gold 2gb ddr2 800 asus p5b mobo ZFZ GEforce 7900gt sound blaster audigy 2 ZS Intel core 2 duo e6600 Antec p150 case. Only problem is that it will not show any signs of life other than the green light showing power to the mobo. I have tried the following: tried a new power source tried a different dvd drive tried a different sound card tried no sound card tried a second hard drive (bought two) returned the mobo, thinking it was the problem-it evidently wasn't disassembled everthing and removed mobo to make sure there were not any unintentional grounds or potential short circuts still will not boot-nobeeps, no nothing. It's been a frustrating week and a half. Any suggestions?
