To START off im not too knowledgeable on computers just the basics. Now for the problem. When i play games online (from a wide range of websites) and play my own games it will start off fine then the game will get slower over time. After a couple of minutes of that the game will go back to normal for a couple of minutes, then it wil start slowing down again. I tried DEFRAG, got the most update DirectX, cleaned registry. Ill put up my system information and compare it to Warcraft3 (going to get WoW when i get more RAM and fix this problem). Please help me out.
