Hi, after buying the CPU the seller communicated with me about fitting it and in the conversation I gave a short description of what I thought was my dilemma, i.e. a possible problem with the CPU or the main board. He agreed with you that it was more likely to be the main board.
Because of the different possibilities and I must admit, my impatience, as I do need to get the main system going again, I purchased a main board from the same seller, also refurbished with a six months warranty. (The same board as mine).
I thought that would cover everything, but as you now mention the switch again as a possible problem, it concerns me if it could harm the new CPU or MB?
When the new CPU is installed, do you suggest I try to boot the system by shorting the pins as before or is your suggestion just referring to the ‘fitting’ of the CPU whilst unplugged? If the system boots by that method, would then trying the switch as normal have a risk to the new CPU (or MB if there is no success with the new CPU)?
Are switches replaceable or would a faulty one mean buying a new case? Sorry all this is dragging out but I would like to be as clear as possible.
