hi markoz & rservice.
well sofar so good,new more powerfull psu fitted and sofar she seems to be working,to early to say if all is well,but shes booted up i am hoping that was the only problem,so i can get back to flying.
but i have seen on ms web site that all updates and support for xp will end in april next year,so looks like i have to saveup for a more powerfull gaming pc that can run fs9,fsx/xplane10.
alan.
