How do I fix the error message 0xc0000005 for gta sa?

OK, so I start gta, and after all the intro and stuff, when I start playing, the game shuts after like two or three minutes, with the error message 0xc0000005. I've tried everything, but nothing worked. I'm not much of a computer guy and barely know anything bout my computer, but I know I have Windows XP, that's all. Can somebody please help me? (Oh yeah, and I just updated my driver for my nVIDIA graphics card thingy, and it didn't work.)
