When I'm running my Shuttle at STOCK speeds (mem is pc3200 running in sync with cpu, relaxed timings) it keeps on rebooting. It can do it when the computer is sat doing nothing, when I'm watching a DVD or playing a game. It also freezes when playing games. This is an XP2500 running at 333fsb which is stock. The temp is going about 44C so I doubt it can be that.
Could it be that my 2 memory sticks just don't like each other?
This is in an SN41G2 btw.
