Fan location is mentioned a few posts back; it's on the rear of the laptop chassis, behind a little vent but it sounds like something is wrong with internet explorer, or the files that it is trying to load.. Before you delete temp files, can you run Hijackthis

Select scan and create log file, then copy and paste the HJT log into your next post; along with what OS and what version of internet explorer you are using. Internet explorer version information is located in the the HELP tool bar menu of internet explorer. Open internet explorer, pres escape before it starts loading a website, so that it doesn't give you the popup error, then open the HELP toolbar menu located at the top of your internet explorer window, from the HELP menu select "About internet explorer", then note what version of internet explorer you have installed, post the version of internet explorer and what OS you are using. I'll take a look at your HJT log and how to repair your version of internet explorer, post instructions etc..

once you get your HJT log and other info posted you can go ahead and delete temp files.

To delete temp files, close all open windows and browsers, open windows control pannel, "start menu, settings, control panel" or something like that. From the control panel double click on internet options, then from the general tab of internet options, there's a "temporary internet files" section and there should be a button that says "delete files", click on the delete files button, then check the box that says "delete all offline content" then click on OK. When it is finished, exit internet options/control panel and restart the computer. Once the computer is finished booting, open internet explorer then browse some web pages and see if IE explorer still has the issue. Most likely you will still have the issue, but it's not a bad idea to clear the temp files on a regular basis. The reason I ask that you post another HJT log is that, it's possible you have got another infection, if there are no signs of an infection in the Hijackthis log, you may need to perform a repair/re-installation of internet explorer. I won't be back online till later tonight. Hang in there, if you need to browse the internet in the mean time, try downloading and installing an alternative browser like Opera or Firefox.
