My HP Envy 4 Ultrabook was working fine until recently when the HP Support Assistant requested that I update my drivers just a few days before the launch of Windows 8. I updated all my drivers and I am getting a BSOD once a day. I tried to update all my drivers again but it doesn't seem to help. I would appreciate if someone can shed some light on how I can fix my BSOD issue. I am thinking of upgrading my notebook to Windows 8 but I am afraid my current issue of BSOD might affect my upgrade. Would really appreciate all the help I can get. Thank you.
