That is good though it still sounds like a power issue. Anyways lets start from the top. Try to reseat all you PSU cables, Reseat all your ram, addin cards (like GPUs, sound cards etc). Anything that has a plug or plugs in to something one way or another...You want t reseat. Test it after doing this. does it help? If yes your all fixed. If no...try running DDU in safe mode. Load the latest driver after you run DDU. Does this fix is? Yes your done. If no...Try running memtest 86. your memory fail (not including rowhammer test...most all ddr3 fails this test but still works fine)? If yes replace it. If it does pass try reloading windows. Does this fix it? yes, your done. No...replace your PSU. Does this fix it? yes, your done. No...replace your motherboard. Does this fix it? yes, done...or once you get to the ordering parts bit you could take it to a tech and pay to see if they can find the part that is not working properly. Otherwise you have to start replacing or swapping parts (if you have spares to use) bit by bit.
