motherboard died

Hi,
So my good old,very loud, noisy p4 motherboard finally died on me. I think my room is warmer in the winter because that beast. And I am a little deaf because,for six long years, the loud cpu fan constantly bombarding my ears. The other day I found an Asus (newer,quieter,faster) replacement together with cpu and memory from the bay for thirty bucks.I installed my old hard drive on it and started the computer. BUT... the XP would not load. It just keep re-starting to the page "Start Window Normally". "Last Know Good.." "Safe mode" all come back to the same page.So what's my options? Re-install XP or do repair install? Re-install may involve call to activation center and Mr.Gate think it's a good time to sell me a Windows 8.That might eventually happen but please not now.Please help.
