why is my acer 5517 laptop failing? 1st. media player will not record, now some time later wont play back any of the music already recorded. 2nd, several drivers aren't working. windows updates quit downloading with january 14 updates. get a constant warning telling me to turn on updates, but they will not turn on from the control panel, act like they do but they don't. and now the computer will turn on but there is no wall paper or start screen only the curser, fully functional. control alt delete gives me the option to use task manager and by opening file the home screen suddenly works. most of theese problems occured since downloading spy hunter 4. but this program has not bothered any of my other computers.
