OP asks for help but does not mention pc model, what to do

check OP previous discussion (if there is one) to find out model 

OP sometimes starts a new discussion assuming community already know his/her pc model

instead of telling OP “we cannot help if you do not tell us your pc model”, check history.

can merge current new discussion w old one if question along same thread

If it is OP’s first discussion then obviously need more information
