CPU at 100%

Hi all

I have small problem. I have found a small script written in aspx and  every time i try to open a page in browser my CPU goes to 100% right away and it take up to 1min or more for page to load.

I have .net Framework 2.0 installed.

The thing is that from the beginning the page loaded ok, but after a month  when i was actually trying to start learing aspx the page need lots of time to load and CPU is at 100% always.

I reinstalled framework, but same thing occur.

Can you give me some suggestions what should I do so that asp.net would run normaly?

Thanks,
