True that you need to be EXTREMELY careful, but we have found that some mother boards ground out via case screws. Thus by trying to post outside the case ( placing the MB on wood or cardboard ) he can verify it's working.
Then if it does not work in the case then MB screw grounding issues are to be suspected. The point here is to get something working, if nothing is working then your only choice it a ground up re-build with all known working parts. Just trying to suggest the quickest route to results then slowly integrate back to a working system. To be Cristal clear MB outside case isolated on non-conductor, PSU connected ( correctly ) Video card connected, then power with case button ( carefully ) You want to see the Bios on the monitor then shutdown. Thus put MB back in case and re-test if it fails then find the ground issue and resolve. Once MB works in case hook up Hard Drive etc. re-test, baby steps On Tue, Oct 8, 2013 at 12:14 PM, Matthias Johnson < [email protected]> wrote: > > > > On Tue, Oct 8, 2013 at 12:04 PM, Chris Knadle <[email protected]>wrote: > >> *Occasionally I hear of people booting their motherboard on an >> antistatic bag or on top of the box that the motherboard came in, but I >> generally try not to do that.* >> > > I have done this though I also wouldn't recommend it.
