Recently started getting problems shutting down my computer - when I go to start -> shut down, I get a "program not responding" error for a blank name program (ie doesn't give a name), and it occasionally doesn't end task when I ask it to (locks up if I choose this).
When I get beyond this and the icons etc all disappear, I then get an illegal operation message for every program that has been running, and when I OK them all it eventually shuts down.
Problem is that a) I'm not convinced all is well if this is happening all the time, and b) quite often it just locks up and I need to switch off manually which can't be too good for my hard disk etc.
Why not go to Start\Run and type MSCONFIG go to startup tab and remove all the tick’s except AV and Firewall and System Tray then try your computer. You can put the above back one at a time until you find the problem Program
Still trying to sort this out, but thanks for the help so far. I'm going to try out woodchip's suggestion next, which is similar to something suggested on the Win98 Shutdown Help Page that's also been linked to here.
If the problem has occurred on a pc which has been shutting down normally and has not had new software added, you may benefit from a bit of routine maintenance. Try deleting unnecessary files (e.g. temporary internet files) and then defragmenting the hard drive.
Just a note to say that woodchip's solution is good for finding the culprit programme, but if you are tempted to leave some items in the startup group disabled permanently, bear in mind that this in itself can cause problems when you start up. (It can cause one or more items to load incredibly slowly and even cause crashes on startup.) Best long-term solution is to completely avoid/replace any programmes that cause problems at startup. They are not worth the bother.
