Thanks ORAC and NAC Inc.
I can try the RAM change fairly easily, given a few days. Encourages a social visit as well.
If that does'nt work and Carrera SSC perform as badly tomorrow (Monday 6th) as they did last week then I think I'll give up (and steer clear of Carrera in future). All Carrera are aware of is that I require some technical assistance .... under warranty.
From research via Google it would seem that Win XP is a mess. Incompatibility issues, amongst others, seem to be rife. If that conclusion is correct, then it's appalling.
Then again, I'm no PC whiz.
Many thanks to all for all the advice and suggestions. I'll let you know if I succeed.
