1.quit all running programs.
3. type "regsvr32 /i urlmon.dll (don't forget space after 32 and i) click ok
4.when you receive the "DllRegisterServer in urlmon.dll succeeded message click ok.
now try your web pages.
if that doesn't resolve the problem repeat steps 2.3.4.for EACH of the following files(in step 3.replace urlmon.dll with each of the file names below.
remember to check web after each one,
hope it works for you.
