I do have the ABIT EQ program. Which shows 'nominal' voltages.
But, of course, that's after windows is up. I'm wondering if the voltages have stabilized by the time windows is up. Perhaps they're low during USB 'initialization', or perhaps when the p/s is cold (i.e. the problem seems worse when powering up after the machine has been powered off for a while - like overnight).
I'm guessing that the only real way to know is to replace the p/s with a quality one from PC Power & Cooling and see if the problems vanish.
I'm also thinking that this might also be a Windows problem, since invariably the actual ICONs in the systray are always in different order (I assume they display in the order Windows starts them). If it is actually a Windows problem, I guess I'm stuck.
