I just did a fresh isntall of Winxp pro on my brand new sata HD, I installed all the drivers for it, so now worries there, the install went perfect, but the first time loading up the Winxp load screen will appear for a split second, then boom blue screen stating problem occured windows had to stop in order not cause harm to the system, check for viruses, new hd drivers or controllers, run chkdsk. What the hell, it has done this everytime after four fres installs.
