How to test memory?

[kalispimenta]

Hello i got some f2-8500cl5-2gbpk along with a w.d.raptor.I re-installed windows and after my games started crashing freezing and getting display driver crashing.One of the questions is "Is the memory good?" .
So i would like to know how can i test my memory and how to interpret if the memory is damaged in anyway.I tried to run memtest86 but didn't know where to look for errors.
Thank You

if you already run memtest, then you'll see errors in red color if the memory is defective
thanks.
