Thanks for the reply John, I can't see a 1068 anywhere but theres lots of 7023 and other 7 series numbers with error by them. CS4 is the only thing (other than my printer) that I have noticed a problem with, couriously CS3 still works but gives a windows spooler sub system application error warning when starting up, I do have a HP printer on this computer, should I try the command line prompt? I am happy to reinstall the printer.
I had a problem getting it to boot up today, it just went to a black screen and stayed there, it took several attempts to get it going, time for a reformat? or something more serious do you think.
Thanks again wayne
