Re: Random Restarts
By random, I assume you mean there is no pattern to the restart... By restart do you mean like, just a spontaneous BLAM, reboot, or is it a STOP error (blue screen) followed by a reboot. That can be caused by device drivers, or windows itself, and the error codes DO actually mean something. Spontaneous crash/reboots are almost always hardware related, I'd look into the power supply and ram (though it could be lots of other things too). And I'm also assuming that since it's a Presario you're not overclocking it....
