Unmountable boot volume
I was on computer yesterday and I was playing Starcraft, and then my computer did a mini restart, then froze. I restarted, it was fine, and then I had computer on for like 1 hour, then it happened again. I restarted, and it gave me an error that windows has to shut down to prevent further damage. It's an unmoutable boot volume, and I can't get passed the windows xp start screen (where the blue thing tells progress). Then it give me the ( i think ) hexidecimal shiz. I don't know what it is and I am pretty sure it won't let me get even there anymore. Any suggestions??
