You messed with other than that.


It sounds like you set your pc to operate in background mode.





When you power up press F8 and get into your computer using Safe Mode.


You can then undo you changes.





Tip: I think you changed your system performance settings.


Check like this





Control Panel


System


Performance


Advanced





Programs and not background services.
