Hi,
The part that is running Windows can be dysfunctional. Or something, such as antivirus,
is really affecting Windows. Even something you have running in Linux could be crossing
into Windows (it happens).
Check the drive : (I would run the manufacturer's diagnostic utilities)
Can you boot to the System Recovery Options? And/or you may need to make a
USB Recovery Drive or a Repair Disk if you don't have one. Installation disc can
also be used.

Disk issues can get serious very quickly so I would thoroughly check the drive now and
be sure to keep redundant backups of your important data (use several methods).
