Problem in computer

hi sir/ Madam,

My computer also have many pop-up boxes. The first one saying that "
wdfmgr32.exe has encounted a problem and needs to close. We are sorry for the
inconvenience".

Another pop-up box saying that " my computer must restart now because Remote
Procedure Call Services Terminated unexpectedly"

Please help me to solve the above two problems. Thanks for your great help.
