Sounds like your computer is never shutting down "safely." I would try making some changes and then set a restore point. Start->Programs->Accessories->System Tool->System Restore. Then try rebooting and see if your changes are still in effect. If not, computer = hossed. If it works, then try turning off system restore. Right click My Computer->Properties->Restore. And then make a couple changes and restart. If changes are still in effect, you should be good. If not, again, computer = hossed. Though, as mechBgon says, it may just be easier to reload.
