Question PC doesn't boot after sleep

[shmuel1614]

Hi.
Long story short, out of the blue, my PC stopped resuming work after waking it up from sleeping state via keyboard / mouse.
At the moment, pressing any key on the keyboard / mouse would result in the pc turning on, hardware starts doing it's thing, but no LEDs and no boot into windows.
To "solve" this, I end up having to force power down the pc via holding the power button, then turning it back on, which boots windows as usual.
The only thing I remember changing in the BIOS was turning on FAIL WARNING OF FAN but I don't see how this could affect the boot state.
I do have "wake up by keyboard via any key" enabled in the BIOS (it was turned off before and would still wake up the pc just fine) and have all HID keyboards and mouse "wake up by keyboard" checked in the properties.
The only thing I remember changing in the BIOS was turning on FAIL WARNING OF FAN but I don't see how this could affect the boot state.
UPDATE: in the running state but not booting, the LEDs are off but turn on for 1-2 seconds every 5 minutes give or take.

Just reset the BIOS and reapply the important settings I had.
