ACPI temperature range help

Hi. I need to know how to find out what kind of motherboard and etc. I have. I got the computer from my mother, and it has a hx of clicking then freezing, or just freezing. I downloaded Speedfan 4.39 and it is showing ACPI temp. of 55c. I think that is a bit high, so I want to find out what is wrong with the computer so I can fix it. I think it might be a malfunctioning fan. Any help would be appreciated.

The clicking nose could be the hard drive failing. It's usually a sign of a hard drive failure.
