I've been having this problem that started a few days ago, whenever I turn on my computor, it works fine for a few minutes and then the task bar and deak top icon become unresponsive. Ctrl alt delete does nothing. Any program I have open stops working and if I'm in a browser it acts as though I had lost internet. The mouse still moves and I can navigate browsers but nothing else works. I have a Toshiba laptop with windows 8 on it. Thank you
