repurposing an original xbox

I'd suspect the game itself,i have 3 games on original discs,never been polished & in as new condition,i can't recall the name of the 3rd game however black & links 2004 although have no issue being read,do have issues once placed on hdd,links in particular more than likely won't load from hdd,if it does there's a good chance it will crash or just boot to black screen,ftp'ing will more than likely make the game not boot,black is opposite it will run may even be able to complete game yet it too can either crash or just not boot at anytime,Americas Army is the 3rd game that plays up.Just remembered halo 2 has seized screen on occasions,no black screen just stopped in game tho not very often,reinstalling can help at least for a time,could be a combination of issues that make shit happen
