Xbox (not 360) power downs

[maby66]

My old Xbox (crystal green, original, yay me) is acting up - the power button wrorks probably about 50% of the time to turn on, and it powers down frequently in the middle of games.
It sounds like the sort of lose connection issue that could be fixed by opening it up...but before I do that.....any thoughts?

Thanks for reply.
Had it about 18months, bought s/hand from a games specialist.
Its been flaky off and on since I bought it, but has now deteriorated to the point that its almost unplayable.
No chance of a warranty repair I would have thought.
