Ram is full on Photoshop? (Surface 3)

I have seen other people writing about this but i have yet to find an answer that works for me. I have had a surface 3 for over a year now and i have love it. Recently i did a windows update and that messed up my pen where when i zoomed in it panned ( i seriously thought my pen was broken) i did some digging and saw it was a bug and was like okay no biggy ill deal till it is fixed. Then this morning i turn on Photoshop to do some photo manipulating just for fun and when i hit the magic wand it would say could not complete (action) because there is not enough memory (RAM). i restarted Photoshop, i have restarted my surface, I tried doing the preference - Performance thing but that gives me another error so i cant.... I even went as far as resetting my surface to factory settings because i thought something in the system was clogging my RAM. It luckily fixed the pen pressure problem, but the RAM is still messed up even though all i have is Photoshop installed at this moment. I don't know what to do i have used Photoshop on this surface for as long as i had it and i have never came into any problems until this past two weeks have been full of them. I can't even save work for crying out loud!.... Please someone help me. Will it be fixed on its own with updates? Is it another bug? I need answers D;
