Blackwidow Chroma V2 LEDs on Numpad stop working

Having an issue where the LEDs on the numpad, indicator panel above the numpad, pause/break, page up/down, and right arrow key all turn off at random intervals and stay off.



from what I've seen they turn off after:

- 30 seconds after a simple chroma effect (static colour with pulse on keypress)

- 3 to 5 seconds after a more advanced effect (red and white cycling diagonally like a Canadian flag)

- seconds after reboot with any effect

- sometimes not turning on at all



the only way I can get them to work currently is setting a simple static colour and unplugging plugging back in up to 5 times and waiting between reconnects for power drain.



I have tried:

- Rebooting (I work in IT so trust me I actually did it unlike my users)

- updating the firmware (already on latest for BWCV2)

- uninstalling and reinstalling Synapse

- recreating effect in chroma studio

- resetting keybinds and profile in synapse

- different USB ports (both USB 2.0 and 3.0, also on motherboard, front IO panel and USB hub)



I have a feeling its software/firmware related since I can get them to work for extended periods of time as long as I use a very simple effect. PC specs below if needed.
