I have been having this issue ever since I replaced my hitachi drive with a seagate drive (that I got as a gift) on my laptop. I have tried several issues to fix this (and revoked a few due to further reading that I shouldn't apply some of those fixes). I checked resource monitor and it seems almost all of my applications except for my games seem to run mostly off the disk instead of the RAM, further proving this is the fact that under system task is pagefile.sys using up the most disk activity. It slows down my laptop a bunch and I would like to fix it. Any suggestions?
