Hello everyone, i have a problem with my laptop acer aspire s3-391. for a month the problem starts when I turn on the computer, 
it took 15 seconds for the BIOS to load the windows 10 system. a few days later, the system load time begins to increase 1
minutes then 2 minutes and now more than 1 hour or it does not load the system! always a black screen. the fan is running
can someone please help me? thank you
