What are some Good Stability testing Apps

[newParadigm]

I would like to build some computers to sell at a local market that goes on every year at the fair in my area.

I want to make sure that they are stable and problem free before I hand them over to the customer.


So I was wondering:

What are the best stability testing apps to run on a PC and for how long should they be run, etc.


I already know of Prime95 and CPU Burn but any help woud be much appreciated.

Could also use the burn in feature of Sandra and 3DMark 200x on a loop test.
