<< Solved >> Help with strange behavior after CPU upgrade

[leech3r]

I just restarted after a few hours of being off. It worked fine for about 5 minutes, then the lines came back in both monitors, so is not a video cable issue. It freezes after that.
Could it be a heating problem? It has a dual fan cooler, but maybe need to apply new paste?

Problem Solved: it was the thermal paste, bought new and now it works fine, it was getting hot fast. Thanks for all comments and realize it was a dumb move not to use new paste.
