Restoring Wins xp pro that has crashed?

Let me backup and start when this problem 1st started. I began to have a loud fan noise at startup. I would let it run for 2 mins and shout down and reboot and the noise would go away This went on for about 2 weeks. I though it was the Heat sink fan. Later I found out it was my PSU fan going bad. Then Wins crashed and I could not load the desktop display. I tried to restore w/ the recovery cd. This failed several attempts. I though the HD had died. So I decided to install Kubuntu to see what was going on. Kubuntu installed w/ no problems., except it is a 2006 version. I ordered the newest version to be sent to me by mail. Now I am trying to see how I can get Wins XP reinstalled. I think a was told that the weakest of the PSU might be the bad boy in this game. I appreciate all the help I can get w/ this problem.
