My experience with the Power Savings on the hard drive was just the opposite; running Win98SE and the CLI version of SETI 3.03, I found that a number of my machines would lock up at night, usually after submitting a WU and downloading another - I turned off the power-savings to the hard drive and the problem disappeared. As for the monitor(s), yeah, I don't bother with the power-saving settings, I just turn the monitor off.
