My friends acer laptop has a freeze recently in a Pes6 game we turned it off and when we turned it on we watch everything as a normal windows xp startup when we came to the welcome screen we realized that touchpad and keyboard are not working. We think Fn+F? but the real problem is keyboard is not working at all. We can't access to bios with F2 at the very first startup. We tried to plug in a usb mouse but no electricity activity can be seen in it too. USB's not working either.But there are no errors and windows seems to start without any problem. Have a suggestion?
