years ago i bought a couple refurb boards for a spare i3 sandy bridge i had laying around. i didn't test them in time to return them. one would crash at random, and after such short periods of time that it was basically completely unusable. the other, an msi h77ma-g43, i couldn't get to boot or show any signs of life whatsoever.
for some reason, i kept both of them.
fast forward to a couple weeks ago, i had need of a couple more pcie slots, so i pulled out the old boards. first try the crashy one. it stayed on long eough to install windows, but won't stay on. and it won't reboot itself when it crashes. so, pretty much useless for mining.
so i moved everything over to the h77 board, thinking maybe i didn't do something right, maybe there was something i could do better to get it working. put everything together, short the power pins. nada. try to look for a jumper to reset the bios, and don't see any (apparently the pins are there but there was no jumper that came with the board, anyway). so i pull the battery, swap it with the one from the crashy board, short the power pins, and walla! life! this dead board works!
i got it hashing away, working great, reboot it a bunch, unplug it from the wall so i can put my power meter on it (pair of 1060s hashing away at ~45mh/s for all of 210 watts, nice). but it's a cluttered setup. the power supply was on top of another computer, with the board on its box and stuck in one of those cubicle shelf storage things. i figure i should at least put the power supply behind the board and cards, cut down on the clutter.
to do this i unplugged the supply, drive, whatnot. put it all back together, short the power pins, and... nothing. not a thing. checked the switch, connections, everything. no boot. not even a whimper. unplugged everything but the ram and processor... nothing. not a thing. tried pulling the battery, changing it for a new one, shorting the cmos reset pins with the handy screwdriver. nothing.
anyone got any clue as to what might be going on?
