My updated stability test
I'm using these softwares to run a system stability tests :
1. Video card stability test :

2. Prime95 :

3. Windows media player (Built into windows) and a short avi video clip (You can use any video file that plays with windows media player
How I run the tests :
1. I install the video stability test
2. I run Prime95 with the option of maximum heat generation
3. I open the video file with media player and in the PLAY menu choosing "repeat" option so the video will play in endless loop
4. I run the video stability test
All tests are running at the same time.
Usually I let it run overnight, And if there's no errors, i consider this system stable.
I also run some temperature monitor software like Everest, But you can use whatever software you like if you feel like monitoring temperatures.
