You said you have an xp home cd. You can try fixing your windows installation.
1.) On the "Windows XP Home" menu, select "R" for repair
2.) as Repair option, select "R" to use the "Recovery Console"
3.) You will be prompted to select the Windows installation to repair (usually just "1" ) Admin password is usually blank so just hit enter
4.) at the command prompt type each of the follow seperately followed by hitting the 'enter' key
- fixmbr (hit 'Y' and enter at any prompts)
- fixboot (hit 'Y' and enter at any prompts)
- bootcfg /rebuild
After that, take out the XP Home CD and reboot your computer and hopefully that fixes the problem. If it still keeps rebooting, then it could be your power supply is going bad, in which case that's an easy fix and you wont lose all your data. A local computer repair store by you will have the equipment to test your power supply and see if it is going bad or not.
