update I was sent instructions by Chris to put it right, however I had turned desktop off for a rest, that is the windows 7 64 bit jaws 11 computer, this time no desktop loaded up or any blue logo for jaws on left of screen I heard the squeak of scanner loading and maybe printer but only thing I can get on desktop is a round bright circle and in it I think it says Dell it is the Dell logo but static, I have tried turning it off and back on nothing better I have 2 external drives on top of desktop they are warm and vibrating,without a desktop on screen the instructions sent in won't work I am very tired this is the second time the dell windows 7 has muted,but at least earlier in day the icons of desktop and Jaws flag were there I am giving up as I have been trying for hours. incidentally I see someone mentions safe mode well if you want safe mode it is an option, if you turn off a computer badly it may on reloading offer you the option to run in safe mode I think it is given a chance to put itself back in shape ,you can do some work in safe mode but nothing stressful on machine,that is not my problem but I have had it happen my desktop is unhappy if turned off badly or if it has crashed my old laptop is a blessing at the moment Dorothy!!
