hey guys, got new 500gb wd sata drive for my brother and it arrived today. He always thinks i cause BSODs on his machine but i said installing HD isn't any problems. Install the HD, plug in all the cables etc etc and boot up. Comes to the windows xp start up screen. Freezes then BSOD. Try to enter in safe mode - loads drivers then restarts. What the heck is going on???? Really need some help with this please.
