I have had to turn off my Win. 8.1 Update, because if it does, or is I get a flag that says I have harddrive issues and I should reboot my system to fix them, on bootup the Scandisk gets to 49% and the reboots. it gets stuck in this loop, so I then use the USB of Windows 10, run Repair, do the disk repair and everything is back to normal. it boots up fine. so, should I just go ahead and install Win.10 or is there some type of fix for this problem with Windows 8.1?
