I baught a new system in parts. Everything new. I have hooked everything up except a hard drive but I can't even get a beep from the bios. The parts are: Asus Mother Board: P3C2000 Celeron 500 on PPG to slot 1 adaptor with auto detect voltage 4M AGP card (not sure of brand. mid tower case with 250 W. power supply 128M SDRAM I notice that checking the 5 volts, without processer installed, it reads 5V. With processer installed it is 4.91V. Is this too much of a change? I have pulled out Ram, video card, and CPU, all one at a time and all together. Shouldn't I get a beep even if the cpu is bad?
