Power Armor Crash

[KingTotalWar]

Ok so whenever I try to put on power armor on this i crash immediately after equipping it, then when I get back on I can't open my inventory without crashing and eventually have to kill myself just to get it off. I know that this is probably something to do with my computer so can someone please tell me how to fix it ( I have a windows vista ). Also this is not about crashes but how do I color power armor I'm pretty new to voltz and don't know how to do that yet. I can use power gloves fine it's only when I try to equip the armor itself. Please help!
