I am having a pc with intel D865GBF M'Board and P4 2.8 GHz Processor. When i try to play flash games and even Excel games it gets slow down. and plays in a sluggish manner. I am having such kind of three PCs and all of them behaving in the same manner.I tried to clear this by installing newly updated graphics driver but didn't made any difference.

Plz help me to sort out this problem. I don't have any graphics card , and I think it doesn,t require any such cards for playing this kind of silly things.
