RUNDLL/Error loading problem, help!

Whenever I start my computer, as soon as Windows loads I get 2 error messages. The first one reads, "Error loading C:\WINDOWS\bs3.dll - The specified module could not be found." The second one reads, "Error loading C:\WINDOWS\bsx5.dll - The specified module could not be found."

I also get another error window that reads, "The file 'hpzimc05.dll' on (Unknown) is needed. Type the path where the file is located, and then click OK." I have no idea what this means or where this file is.

Any help on this would be greatly appreciated, thanks!
