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 ​
