Hi. I just got back from a long vacation and I intended to come right home, plug in the computer and play a few rounds of America's Army. Unfortunatly, when by brother plugged in the computer and hit the power button, almost nothing happened. By that I mean that when he hit the button, the power light would flash once, there'd be a kind of whine noise and nothing else. No fans would run, no beeps, no nothing. I've unplugged everything from the mobo except for the cpu, atx-24 and 4-pin connecters, front panel connections and the cpu and chipset fans. I always get the green ready light below the PCI ports whenever the tower is plugged in, but nothing else. At some point while I was unplugging things and removing cards, I lost that power light flash. I've done a ten second power supply cycle, it's set to 115V, and I've reset CMOS twice. At this point, I'm at a loss. Any help? My applicable specs are: Asus A8N-SLI, Athlon 64 3500+ and a four hundred-something power supply. Thanks for any help.
