wow I have seen that video and thought that all that was a lot of work!If this was a desktop I would suggest that some part got dislodged in moving it...but since it is a laptop, they are built for movement. Can you press F8 to get into the boot menu? When you say lights...is this the power light? What about the hard drive light showing that the hard drive is working? I am presuming that this is not an error caused by a virus or something that you did.If you have tried the memory, made sure it is in correctly, clean and dust free.Then I would try a different hard drive...you can use another laptop hard drive. You could also put the hard drive in an external case and do a few checks on it...chkdiskHave you inserted the windows cd to see if it will start?
