WIN XP SP3 When I shut down windows loose all setings how to stop it

After bad installation that BSOD my laptop I recovered but I'm unable to
load USB 2 drivers machine locks up. I can only keep it going for more
than 30 seconds if I disable PNP service. With PNP disabled uninstalled
SP3 and then started PNP service all the drivers load up correctly all
devices work ok anything that I connect is recognized and installed.No
errors in system and application event log , everything works perfect
until I execute shut down at which time windows obliterate all the
settings .On next boot windows come up in some sort of default "crawl back
home " mode VGA resolution,touch pad is working desktop layout gone
nothing else works and it locks up when trying to load USB2 drivers
usually in less then a minute. The only thing I can do is swipe the hives
and start again > How to stop this self destructive behavior . I had it
going three times buy now and always the same thing happens . Any
suggestions I'm scratching the bottom of the barrel an getting desperate.
