Gigabyte X99M-Gaming 5 startup issue

[washo]

Hi,

PC was running fine, was left on overnight and when I came back to it, the PC power light was on but monitors were not responding. When I held down the power button to reset, this did nothing and I had to turn off the power.

When I turned back on the PC sounds as if it is powering up, however none of the monitors come on. The motherboard shows 2 orange LEDs lit and the power button on the mb is orange. No error code.

Is this a mb issue or something else? I have removed the graphics card and RAM sticks but no difference.

Any help would be appreciated. Thanks

Hi,

Do you know for sure your PSU is still good? Once you've checked that start with as minimal (but functional) a build as possible. Try using a single stick of known-good RAM in slot DDR4_2_B to reduce the number of variables, if possible. Verify your GPU is good by either substitution or testing it in another system.

If your hardware checks out try booting using the backup BIOS. Throw BIOS_SW to its alternate position and see what happens.
