A good solution is to go to:

Install the software, free for private use, and run. The report you get back is comprehensive to say the least. It will tell you the details of your motherboard, BIOS, the hardware which is connected to the PC, and even all the serial numbers or keys used to install your purchased software. Throughout it gives versions of the software installed, so you can see if you have the latest version.
It is worth printing out the report and putting it to one side in case you ever need to rebild your PC.
This software has saved me hours of work in the past.
