If you think your computer can support running Mac OS X 10.4.3, then you can “TRY” to install. Please do backup your files before you begin.
First step is to get the Mac OS X 10.4.3 installer which is in .dmg format.
Usually the filename is macosx_10.4.3_8f1111_for_dtk_userdvd.dmg and it’s 2.80GB in size.
I will not teach you how to get it, but you can use your friendly google search engine to search and read up on how to obtain the .dmg file.
