My desktop has several links to different web sites that I use frequently,now I can't open them

Originally I had the FireFox browser for beta testing,but the laptop B120 I own became slower and uninstalled that browser and reinstalled the IE 7.0 but now I can't open any of the links I have in my desktop to access some web sites but If I open the IE 7 and type directly the address of the website I want,it will open it,so what's wrong with my desktop that don't allow me to open any link?

What you are referring to are "Shortcuts" rather than "Links". The only way to solve the problem is to "Delete" the "Shortcuts", one at a time. As you delete a "Shortcut", go to web page it pointed to and select "File" followed by "Send" then "Desktop as Shortcut". Repeat this for every "Shortcut" you have. All your "Shortcuts" will work now.
