I would seriously try OCCT for 2 hours or Orthos for 6 hours as well. A lot of people around here will tell you the same thing. One of those tests run for that duration will really prove if your system is stable. I'm not trying annoy you, but it's probably just a good idea to run one of those to be 100% sure IMO.
listen man.. ur not annoying me.. I appriciate your help big time..
i will let orthos run all nite.. and if there is an error i think it shuts off.. and i will report to you all in the morning.
