IE and OE

I have Windows XP Pro on my computer and i am having 2 problems.

1. When i click on my IE and go to any web site I sometimes have a runtime error message.
How can i stop this from appearing.

2. When i click on my Outlook Express icon or start it from my menus. It takes a while (sometimes 1 minute) for the OE to open up and start giving mr emails.

How can i remedy this to speed it up
