You could be looking at a supply or board problem where you won't hear any audio alerts yet see the power drop right off on you. Windows would likely hang on you after you have already passed the option to press the F8 key for the safe mode option since you installed on a different system.
But that will still see Windows load while not being able to run correctly at times. The supply, possible corrupted bios, and especially on an older case weak battery on the board itself are more likely things to consider.
