Computer basic assessment / health check program?

Hi all

Something that's come up at work is being able to offer a free computer health check or basic assessment to our customers as a way of generating new contacts and customers, and give them a free report.

We have been looking around at whats available and all the rubbish that is a waste of time.

Ideally we would like the program to run some basic tests memory/ hard drives/ etc and then produce a list of items and also anything with problems in a very general sense.

then we could point out areas where they could improve the pc with our help of course

I will only want it to take a max of about 15 mins per machine and produce a couple of pages of report ideally

They are all home user machines so detailed networking is not necessary

Question is has this been done in AutoIt?

Or can you recommend outside software that will give me the reports i would like to produce?

many thx
