Motherboard: z77 Mpower LGA 1155 "Big Bang"
CPU: Intel Core i7-3770K 3.50 GHz LGA1155 CPU
Graphics: Several available but prefer the GTX 660
RAM: Kingston Hyper X Kingston 16GB 2400MHz DDR3 CL11 DIMM 4x 4gb (16 Total)
PCU: CoolerMaster Silent Pro Platinum RSA00-SPPAD3-US 1000W Power Supply OR Corsair CX600M
So about a month ago my computer just plain would not power up. I could not figure out what was going on so I called MSI.
Several USB ports and the onboard audio had stopped working a few months back but it still functioned fine.
But not powering up is an issue.
So I did an RMA and got this identical refurbished board back.
Plugged everything in like normal, with the exception of the power supply, I used my back up just in case it was the one that messed everything up.
About a week later I went to turn it on, same thing it was doing before.
Now I can get it to boot up and load windows, everything is fine EXCEPT if I go and plug in a GPU into any of the PCI express lots OR if I connect the Jpwr3 power connector on the mobo into the power supply.
as long as nothing is plugged into a PCI express slot and the JPWR3 is unplugged it boots right up...
I tried clearing cmos, I tried switching to the second BIOS, disconnecting the battery.
Nothing will let it power up, and if I do connect a GPU and try to power up, it flickers on for a microsecond and will not do anything unless I completely disconnect power and unplug the graphics card.
Did I just get the short straw and get yet another defective motherboard?
