doesnt boot up, nothing on screen. cmos battery was stone dead, replaced. doesnt even get a bios screen, nothing. this one has an azus AT31ont-1 board, 1 gig ram. it has a flash drive for operating system. with or without the drive in it, i get nothing. the power supply also doesnt turn on. you do get a little blue led on the motherboard, but no PS fan, no 5,12 volts. i now have it on the bench with an ATX power supply jumpered to always turn on,and a vga monitor. blue led is lit , 5, and 12 volts are present, and still get nothing. documentation seems to be non existant, i cant find anything. its from a video game, and im sure the bios was set to power up when the 110v switch is turned on. there must be a way to use an "on" switch like a pc, to get it into the bios screen, but i havent a clue what to jumper.

any help most welcome
thanks
mike
