Try running "Chkdsk /F C:" in cmd. Hit Y to have it check next reboot. Then give it a restart .

System is less than 0.2% fragmented and regularly maintained. There are no unusual noises as yet. No drastic system changes of late either.
Is this the start of drive failure or is this something thats gone wrong in the OS?
Luckily I have a new build under construction and the important stuff on this drive is backed up, but it's hugely annoying.
