Hello,
My Sony vaio has been acting very strangely the past month. The keyboard stops working then the screen will become distorted and go from being very bright to very dark. I have done a full restore then installed windows 7. The pc will malfunction and be unusable for days then it will work fine with familiar symptoms slowly reoccurring.
