Hello, I recently re loaded windows xp on my computer and now I have no sound. Every time I turn my computer on it says it found new hardware and tries installing drivers for realtek '97 but when I got to install it it says that the driver isn't signed my microsoft. I hit continue anyways then my computer shuts off and this blue screen pops up. I have nooooooo clue what to do and I've tried installing every realtek driver but nothing works

Someone please help me. Belarc Advisor gives me this:
