My gameplay lately has been terrible, I play games such as wc3 and recently Latale and I can play the game smoothly and perfectly for maybe 5 mins( for Latale and wc3 can take up to an hour or 2) then a terrible lag occurs and it feels like im running on dial up where everything is extremely slow. It definately isn't my graphic card or internet, but I have 1.9G of Ram and when I check task manager while running these games it says i'm using 1.3G of Ram Should I get more ram? I've tried defragging my comp and virus scanning and its all clean.
