try using ths one that comes with windows first.
My Computer - select C-drive - right click select properties - select tools
- click check now - check 'auto fix...' and 'scan for and attempt...' then click start
- will receive message 'the disk check could not be performed...' - click yes and restart windows. will come to blue screen and dun touch any key let it count down and start scanning and error fixing...depend on your disk size go for a cup of coffee or window shop at a nearby convenient store before returning to your computer again.
