I have a problem with my computer, basically the function key. I used the on screen keyboard to see what was wrong, when i press the CTRL there is no effect on the on-screen keyboard and when i press the FN key, the CTRL key shows to have been pressed on the on-screen keyboard. I've tried making changes in the regional settings but still nothing. Could the problem have been caused during the installation of windows? My PC is running on windows 7, 32bit. PC-E system sorrento 1. Please help me out cause i can't turn on my wifi.
