Looking for Duplicates Highlight Whole Row

Hello Everybody,

Let me explain exactly what I'm trying to figure out. I am looking in every row starting in Columns P, Q and R. It will go to the next row below the first and see if those columns have the same exact value. If it doesn't it goes onto the next row. If it turns out that row 1 matches row 2 then the program will then check to see if columns A-O in row 2 are all empty. If they are all empty then the entire row of Row 1 will be highlighted Red. If A-O are not empty it will skip over that row and go back to check columns P, Q, and R. This program would run until it gets to four empty rows in a row and then it will stop. I know it might sound confusing, The program is basically combining two worksheets and I'm seeing which files need to be deleted by marking it red. Thanks for your help.

I also forgot to add that after it makes Row 1 red it would then need to delete Row 2 completely. And then restart the program and move onto the next row.
