|check wattage printed on on pwr supply, upgrade pwr supply to higher wattage esp if under 200w and esp if you have lots of|
extra load (cd's etc.) i know this sounds lame, but all i can
think of. (might also be the case: current pwr supp is failing,
result in lower watts supplied to mbd.) If desktop, easiest option is to just try another ps. and see if problem persists.
