Hi recently my computer boots but shortly after my 2 displays shut off and I can't turn off my computer with the front switch, I have to unplug it from the wall I tried reapplying thermal paste and blowing all of the dust out and it still does it. I was wondering if anyone could give me a answer to which component that may be causing it so I can fix/replace it. Thanks for your answers
