Failure-Security Options.

I have an Acer Aspire 6920G with Vista Home premium 32 bit 4GB Ram an
yet experience a lot of hanging and very slow in opening a web page

I have run RegCure, Advanced Windows Care Pro and Glary Utilities an
it worked fine initially but now this problem of hanging still exists.
ran the 3 utilities to ensure all the problmes these utilities suppose
to get rid of

I had a computer techincian to check my laptopn and as they canno
solve this hanging problme they said it must be the hardware

Please assist. Thank
