Hello, yesterday my computer got updated without me noticing, I didn't shut it down for a night just put it to sleep. After waking it up some issues occurred: Firstly I couldn't adjust my screen brightness nor in menus, nor with keyboard (fixed after a restart).Computer was dead slow, settings menus took ages to open, some of them didn't open at all.Many default programs for file extensions were changed (.pdf, .mp3, .mov, etc.)Restarted my computer: The system boot now takes OVER 4 MINUTES!! Used to be ~1 minute mark.Some settings in some applications were set to default values (e.g. Open Broadcaster Software).When OS boots, I get this error message Asus A45V. Please help me to get my computer working properly again. Will provide any other useful info. Thank You.
