I'm trying to get a windows pc working again after a few months of disuse, and have encountered a problem. Every time i switch the power on, the buzzer on the motherboard sounds intermittently, and the computer won't start-up. I've tried unplugging all non-necessary PCI cards, changing the ram to a different slot and reconnecting the jumpers, but no joy. Anyone got any ideas as to what it might be? It's a Gygabite GA-BX2000 motherboard.
