how do i minify my asp.net pages

You cannot do very much with html or the axd pages.
Take a look at this article to get you started focussing on other elements of your website.

well, i did all the others, but on google pagespeed says that i should minify the html and also minify the WebResource.axd and the ScriptResource.axd

is this normal?

Yep, Google tells everyone things like that.  Some of those things can't be done unless you control your own servers (which Google does of course).  Some can't be done on shared hosting because they will never give you access to do them.

I have an Virtual Server. if there is anything that can be done, pls let me know

Virtual Server with windows 2008 and iis

if you've minified your javascript then there is nothing more you can do
