I installed a GA-78LMT-USA motherboard, a GEforce GTX650 graphics card, and when I turn the computer on, I see the 3 fans start and then the computer turns off. Help
Is the CPU fan spinning when starting the board?
What CPU using? Yes it is spinning. AMD FD6100WMGUSBX FX-6100 Processor - Six Core, 8MB L3 Cache, 6MB L2 Cache, 3.30GHz (3.90GHz Max Turbo), Socket AM3+, 95W, Fan,
Try starting the board outside the case. Install single RAM stick, graphics card, DVD drive, keyboard and mouse.
It might be a short related issue (a standoff shorting the board).
I don't recommend putting in the gpu outside of the case as it doesn't have screws to hold it in. If something nudges the table or whatever its on its quite possible the gpu/mobo pcie connector could snap under the stress.
