Tried everything, not overheating, have enough ram, made a paging file, factory rested several times, underclocking, updating and downgrading drivers, and no results. All these methods / “solutions” do is give me a few hours before it starts happening as much as it did before.
There are some other tips in the sticky about this issue: "Your Rendering Device Has Been Lost"
If nothing there helps, post a dxdiag.
