Hi my Arduino Uno stacked with a motor driver shield was working perfectly however I am using the same board for a while now and suddenly my board stopped working. When I upload a code no matter what code is the LED's on the board respond however the code is not executed it does nothing , the board doesn t even beep anymore. Is there a way to clean the memory or something? Please help.
To check if you really cannot upload anymore (assuming it's not a software error), try the following sketch
This will blink the BUILTIN led.
There is very low chance to wore out your memory, you can write lots of times to it (like 10,000 times guaranteed, in practice mostly more).
But there can be another hardware problem, but first check if this simple sketch works.
Also (based on jsotola's comment), remove shields/wires.
Especially wires/shields using RX/TX since these pins are (somehow) used for loading a sketch.
