Need some suggestion on computer lagging. Condition: Window XP, IE 6.0, PC-cillin 2006. When I log on to play RS, everything is ok for the first half hour. But after half hour, it starts to lagging. It happens all the time these days. If only I shup down the IE, and launch another IE. It is ok again. I have used "Disk Cleanup" in system tools of Windows to clean up all the garbages. And also, I deleted cookies, deleted all off-line files, deleted histroies of IE. But it is not help. What should I do now?
