Hi Gray

,
Hengis is offline at the moment, I hope that you won't mind me chiming in.
When you install Belarc Advisor, there shouldn't be any point where it asks you for any input, certainly not about temperatures, it should just come up with a web page giving you specific details about your computer.
Check to make sure that you installed Belarc Advisor, there should be a Yellow Pentagram with a Green B inside it as an icon on your desktop.
If you cannot find that, perhaps you inadverntently installed a different program. Try reinstalling Belarc from my signature. It is a pretty terrific program for determining aspects of your PC.
Look forward to your reply,
TTFN
