[SOLVED] Genuine UNO R3 resets every ~10 seconds (random)

hello, come seek of community because arduino uno had fried it's atmega328 last month (replaced) starts show serious unstability

i left entire night running heavy sketch (my mini-domotics controler project - display , rf control through nrf24l01s) check script's stability, , now: resets every , then, randomly.

first thought maybe went overboard on whole "being asshole ram", since display libraries assholes ram. free of wire , without code keeps on resetting randomly .....

i've become caring of uno don't could've gone wrong?
i tried few different wall outlet supplies, desk computer, 2 laptops, macbook air ... nope still resets, not power supply issue.

any hint causing behavior? in advance.

~ lost newbie.



edit: re-flashed bootloader - problem still persists.

running heavy sketch

my first guess running out of memory.  heap collides stack , function returns go off strange places, causing error resets processor.

if have .print("string constant") calls, try changing them .print(f("string constant")) keep string constants using valuable ram.
