never mind i fixed it....by doing this

1. i took out the battery
2. press and held the power button for thirty seconds
3. plugged in the powercord (left the battery out) and powered on my computer
4. a screen showed up saying that windows is fixing the problems
5. waited for it to do its cycle and restarted my computer
6. waited for it to load and restarted it again to make sure it was working
