Desktop disappears

i’m new and hope this is an appropriate question for this forum?i am using an older dell latitude laptop with windows 2000 pro.just recently my desktop icons and shortcuts and folders…everything but the background picture disappears.control, alternate, delete brings up task master but the only thing i can do is click on shutdown in taskmaster and restart.everything comes back after restart but then out of nowhere at times it will happen again.i also can’t get it to shutdown unless i turn it off manually.:confused:

Do you have any anti virus/malware program installed? Have you tried running a virus scan? When this happens and you press alt/ctrl/del do you see explorer.exe running?
