help me please

[King Hadas]

So I'm having a few troubles getting Fallout (the video game!) to play on my computer. Whenever I try to install it normally I get an error saying the game isn't compatible with my version of windows (I use windows XP) which doesn't make a whole lot of sense to me but who am I to argue with my computer! Since I can't figure out a way to circumvent this I tried installing the game through dosbox which works but now when I try to play it the sound stutters, I can get the game moving at a manageable speed but I can't seem to fix the sound. If I could get some help here I'd appreciate it, I just wanna play fallout (the video game!).
