Step-By-Step Solution:

Initial Grid

                    
First step - add in all possible valid pencilmarks.




For column 1, Number 4 is only possible in cell (1,3)









For row 2, number 4 is only possible in cell (8,2)









For box 3, Number 9 is only possible in cell (7,3)









For row 3, number 7 is only possible in cell (9,3)









For row 9, number 7 is only possible in cell (3,9)









For column 4, Number 2 is only possible in cell (4,3)









For row 8, number 4 is only possible in cell (7,8)









For row 7, number 3 is only possible in cell (5,7)









For box 2, candidates for 6 are all in row 2, so you can remove candidates from other blocks.









For box 8, candidates for 6 are all in row 7, so you can remove candidates from other blocks.









Either candidate for cell (4,2) forces 8 into cell (7,7).









Either candidate for cell (4,2) forces 8 into cell (8,6).









Either candidate for cell (8,5) forces 8 into cell (1,8).









Either candidate for cell (4,2) forces 6 into cell (6,7).









Either candidate for cell (9,6) forces 1 into cell (6,3).









Naked Triple for 5, 6 and 8, can remove these as candidates from other cells.









For box 5, candidates for 8 are all in column 4, so you can remove candidates from other blocks.









Either candidate for cell (5,6) forces 9 into cell (3,7).
