my computer is sooo broken and i need some advice... it keeps freezing, and brining up runtime errors when u bring up web pages, then when u turn it on it comes up with a blue screen and says there has been an error, then a black screen saying memory has been lost, then a screen about ac adaptor something.... and then it will freeze booting.. but sometimes it works.. i tried to reload microsoft and reinstalled my virus stuff... any ideas???

thanks u!!
