Disable ReadyBoost if you are using it
Run SFC /SCANNOW Command - System File Checker

Di you enable ReadyBoost on your system?
ReadyBoost uses external media such as flash drives to boost up the system

Did the SFC /Scannow and it says
"Windows resource protection did not find any integrity violations"
also checked the hard disk drive with the HD tune pro error scan and it was all ok.

i am not using readyboost on any flashdrive or external media
and cannot find it in taskmanager also.
But how should i be able to enable and disable it.
