Sandra,
Use PC Wizard 2009. You can install it, and one of the available things is temperatures. It will tell you the temp of the CPU, the mainboard, and other stuff.

What bothers me is that the other programs are still running. What I would suggest doing, in addition to checking the temps (40ºC is a good operating temp) is to turn off the power, remove the power cord, open the unit up and reseat the memory chips. Take them all the way out and then reinstall them.

Look at the fan sitting on the CPU, and see if it has a lot of dust and stuff. Carefully, as you might break it, vacuum out the fan, or blow it out with compressed air, as well as checking of other blockages of airflow.

Check to make sure all the connections are correctly in place.

Run the defrag, definitely use Spybot Search and Destroy, don't forget to update it before you begin, and also run a new A/V scan, maybe with Avast, or AVG, or some of the other well known free ones.

Any questions, let us know.

I'm blessed watching God do what He does best. I've had a few rough years, and I'm still not back to where I want to be, but I'm on the way and things are looking far better now than what they were!
