Nettet1) Disconnect everything from Arduino especially from Tx Rx pins, and try to dump the blinky sketch. If it works, then arduino is good. If it doesn't work, follow this article to burn a fresh bootloader in your atmega. Check again. If not able to burn bootloader or code afterwards, get a new atmega IC for cheap and replace the damaged one. NettetRemove it, remove the resistor inline with it, or cut the track powering it. Either that or resort to electrical tape (or blu-tack). You have absolutely no control over it. More annoying is the "TX" and "RX" LEDs. These blink rapidly when data is being communicated over the USB-serial connection.
