LNS under heavy load shutdowns my system, it simply powers down. (it got to be lns, now i use jetico and don't have this problem) I have Windows XP Sp2. My friend also has this problem, under heavy load his system restarts itself. He uninstalled lns and the problem went away. He has Windows XP without Sp1. It is most noticeable under World of warcraft but it can happen with anything. Could someone tell why this happens?
