could be, or it could be a problem with the psu cable, i'd unplug each cable, at both ends when you can, and replug them, that often helps. don't forget it's possible that there is an intermittent problem and it's playing games with you by working now, i've had that joy myself before. also check the psu during boot if you haven't, that's when the hard drive loads it the most heavily and it's easiest to see a problem.
you might also try plugging in another hard drive or two to the power cables to load the supply more heavily and give it a better test, you can use old scsi or ide drives, you only need to connect the power lead, you're just using them to load down the power supply and make a marginal problem more detectable/obvious. also it would be wise to check the outlet ground, without a ground odd things can happen sometimes. ps, no need to pull the modem card except to see if it's the problem, which is unlikely (though certainly possible), it's power draw should be negligible. also of course make sure the pram battery is in the right way, and since you apparently do have access to a meter check it's voltage with it in the mac, you should be able to do that. it might also be worth resetting the pmu with everything pulled in case for some odd reason detecting the video card etc. is making it corrupt itself. also of course, if you haven't already, make sure that all of the fans are running. of course if it's still under warranty and you're close to an apple shop (i'm 5 hours away from the closest one, there are draw backs to living in sparsely populated wyoming), hopefully it wouldn't take them long or it could be a known issue, if it is still under warranty a call to apple support might be a good idea, especially if it's a known problem with a hopefully known solution.
