Have you tryed typing " Msconfig" in the run dialog box and going to the start up tab and deselecting programs that startup that you know you do not need? Also there could be alot of bloated hardware or in other words preinstalled hardware that could also be slowing your system down. Im sure there are a bunch of other things that could possibly be the problem but thats all I can think off right now.
