Windows 8 dll error message

Hi experts
At the time when windows 8 RP arises from hibernation, I find three error messages on top of each other and all are same error message.
EAccess violation for SHCORE.dll. I searched in Google but got no answer.
Please help me to solve it. Thanks in advance.
Application Error
