When I turn on my laptop, it loads normally and then an error message comes up before I can do anything. I'll find out exactly what it says later, but it says something needs to close, sorry for the inconvenience. Then all my desktop buttons and start button disappear and I can't get them back! If I go onto safe mode the same thing happens. I can open the task manager in safe mode and open explorer to get the desktop buttons to come back for maybe 5 seconds before they disappear again. In that 5 seconds I can open up the internet. I tried downloading programs to fix my computer but it just comes up with error messages before it finishes scanning my computer and shuts down.
