on my windows password screen, where is has a link in the lower left hand corner to turn off computer it says "turn off f" What could cause/fix this. Since I have noticed this I have not been able to connect to the net at all. Any help would be great.
sounds to me like spyware press f8 when the computer is starting up to bring up a boot menu. select safe mode start up your pc in safemode and run a system restore to a point before you noticed the problem, this should fix it. also id get yourself some spyware protection like adaware once its fixed
