I have a Gigabyte H61MA-D3V I bought a couple of months back for these Fortnite builds. Been working fine when built on test bench. Transferred it all to its case and now it will only boot up once I have taken the 24 pin power plug out and back in again. Then it resets BIOS back to 2012 ! If I leave the kettle power cable out of the psu but leave the 24 pin plug in for just a few minutes, and then put it back in, it won't boot. If I leave the kettle plug in all the time even with pc switched off it will boot up normally every time. I can't send this over for my mates kid to use like this. The other build is working fine. It does it on 2 different PSUs, one brand new one and the one on my bench. The light appears on the GPU even when pc is off so power is getting through to the board. It just won't power up without dicking about with the 24 pin plug. Bit desperate now as I will have to find another board and a copy of windows 10 as this had one with it. Any ideas ?
