No system resatore points

I guess you mean XP Home.
The first thing you have to do is right-click on My Computer and select Properties. Then select the tab marked System Restore. When that opens, make sure there is no check mark in the box labled "Turn off Sytem Restore...drives". Then select your installed disk(s) and click on Settings. Make sure the slider is moved to the right at least halfway (or more if you have the space).
You can also test restore by creating a restore point manually and then coming back to it in a day or so and confirm that the one you created is there on that creation date.
Luck!
