Password
My old computer won't take my password so how can I get into my computer and I can put in a Windows 10 If can get to the Internet because I don't have the Windows 10 CD?

It depends what password you are talking about.
Windows user account password?
Bios system/master password?
If you are not sure, take a photo of it asking for a password and post that picture.
Which OS is on it now?
You can make your own Windows 10 InstallUSB. Installing Windows 10 will overwrite the entire contents of the disk including wiping the original user accounts [so their passwords become irrelevant].
1 Download the ISO - use one of the sources identified in Download Windows 10 ISO File -TenForumsTutorials [one of them, the MS MCT tool, achieves both steps 1 & 2]
2 Create Bootable Installation USB - TenForumsTutorials
3 Clean Install - TenForumsTutorials
Best of luck,
