i have a hp pavilion 740n and ive been recently installing drivers for SiS sound, graphics, and everything else. when i installed it the first time, my sound was not working at all. so i rolled back the drivers and reinstalled them. when i was doing that the driver search on their website told me to get another one. while installing 1 could not be installed so i finished without it. after i did all this i restarted my computer and now whenever it gets to the end of the windows xp loader my computer crashes and goes back and starts loading up again.
i need help without emptying my entire hard drive.
