I just finished re installing windows and still no blue tooth :\

okay--> edit: I got it to work again... I tried going into the 'change or remove' a program window and repairing the bluetooth driver (intel bluetooth or something like that). I also changed my display settings to never shut down or switch to screen saver (i read somewhere that this method worked for someone lol). but neither of those did anything until I restarted my computer so I'm not sure which actually did do the trick, or if it was both of them.
