error "nview_info warning "userenv"

Greetings all;I hope everyone is well.My "irritation";being the above 2 msgs that continually show up on my event recorder.??Anyone know how to resolve this;if it needs resolving? The warnings usually precede the error.I use a hp7680 media centre;with upgraded gpu from geForce 7300le to 7950gt oc. processor 2 duo e6400;hdd 500gb. desktop;cable/2wire. using laptop wireless on same network.Hp techs have no ideas;I've tried reconfig both pc's.Could it be the flight sim(15 gb0;or the laptop????.Systems work .The laptop uses vista premium;the desktop uses win xp. Both work fine;no screen desktop display error msgs;no crashs;gpu seems to"pull it's weight ok." thanks jerry
