The thing I really like about this, is its toolbox, It has all kinds of great OOW programs for controlling the windows OS, One of my favorite = Smart ram, Just run deep scan a few times and you save up a ton of ram (Though this problem only seems to affect me since for some reason, My graphics card`s EATING my memory alive. Nxdsync, If I have it up for more than a day, it jumps to 700 megs of ram in use, Then up to 1,6 gigs of ram in use, and just rapes windows.
Also for win7, Its better if you increase your pagefile system capacity abit, Also, I suggest you get more HDD space, 160 gigs I couldnt live with.
Mind taking a screenshot of your resource monitor and show what is eating up all of your ram slowing it down?
