How can I tell if it's the I/O board or the motherboard?

文本:

Water damage! Worked for short periods of time, then quit completely after about 2 weeks. Rather than replace BOTH, how can I test with a multimeter to know if it's the I/O board or the motherboard which is bad? There must be some way to discriminate between the two?
