Hi, I have a Dell Inspiron 1545 computer with windows xp . I have several error messages pop up one after the other when I start up my computer. Several have little square boxes. They say things like Windows cannot find ' squares' make sure you typed the name correctly and then try again. To search for a file, click the Start button, and then click Search. What should I do?? one says Could not load or run ' several squares' specified in the registry. Make sure the file exists on your computer or remove the reference to it in the registry. I am not advanced need help. Thank you.
