I have been using Windows 10 since day 1 and haven't had any problems. Recently, whenever the computer reboots, it gets stuck on the black screen with the Windows flag and the spinning circle freezes. I power down the computer, and try again and it try to repair but it also freezes. I have to power cycle the computer about 10-15 time until I get lucky and it boots successfully. I use the computer for a week or two without issues then when its time to reboot, I have to go through the same process over and over. I have booted up with all the USB's unplugged, I have ran a memory scan and a chkdsk. What else can I try before I reinstall the OS?
