Your system load at that point should be pretty low and I'd be curious whether those voltages come back into range better. Be sure to do some reading on sensors and make sure you're configured properly. Also do some tests: check the sensors (or run some daemon that reports them for you) and then add loads to the system to see if they fluctuate with more load -- do a find on a dvd with a big file tree, or cat /dev/dvd > /dev/null to get the drive to spin up and watch for fluctuations. throw in some big cpu eating job adn watch it some more. If your voltages fluctuate more as you increase the load, I'd vote for a power supply. If you have another power supply available, try swapping it out and see what happens. I am NO EXPERT in this at all, so don't go buy a new one on my word alone... Maybe you can borrow one for a few minutes... Somewhere I read (maybe here) that the power supply is the most common point of failure after hard-drives... A
