One problem, though-- every so often, the monitoring software (that came with the motherboard) reports that either the PS fan or the CPU fan (or both) stops functioning for a moment or two. Once, this actually caused the system to shut down.
Thing is, I don't think the fans ARE actually stopping. I'm not sure what's happening, but it's making me crazy. I've updated the bios and the chipset drivers, uninstalled LiveUpdate (which I guess causes some problems) and reinstalled the monitoring software. After I did this, everything ran fine for hours last night.
Today, it's started again.
I still have the new unopened motherboard ready to send back to newegg... and to be honest, this is so annoying that I'm half-considering starting a THIRD RMA and installing the new board.
Any clues what could be causing it?
