user48726: Update:
The arduino works only when I connect 3.3v to reset pin. And I successfully uploaded a sketch but it stops when I disconnect 3.3v and reset.
Update 2:
-- Removed --
Update 3:
Its working perfectly and running smoothly for like 5+ min but the problem starts again


I bought a new arduino nano V3 clone. Till now, I have been facing very strange problems with it:

The pre-uploaded blinking sketch works for a few seconds (like 5 sec and only works when powered after a break) and then it starts to glitch
The L led stays on or off after that
Reset button does nothing (No led blinks or anything)
Can't upload any sketch
Programmer is not responding
RX led blinks during uploading (3 times only)
USB not recognized when connected

Here is what I tried to solve:

Loopback test > Successful
Changed ports
Changed proccessor
Tried uploading with parallel programming
Sketch worked with another arduino nano clone
Manual reset
Tried with Old bootloader
Tried uploading sketch with older version of Arduino IDE.

Here is the exact image of one I have:

Here is the error message:

avrdude done.  Thank you.

Problem uploading to board.  See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

What is wrong with my arduino?
Note: I was uploading the blink (Example) code, tried with others too...

It seems your AVR is not updated, try to update your Arduino Avr Bords on the boards manager. also make sure your avrdude.conf file might to be :

Dont forget to wire RX to GND or connected RX to TX directly.
Hope this helps.

user48726: When soldering the pin headers, I used too much flux. So this caused contact between the GND and RST on the ICSP causing the arduino to stay in the reset position. I removed the ICSP pin headers and there was a lot of flux. I removed it and now my arduino is working perfectly. Thanks to @Juraj for figuring it out that there must be a contact between GND and RST

avrdude done.  Thank you.

Problem uploading to board.  See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

<p>What is wrong with my arduino?</p>
<p><sub>Note: I was uploading the blink (Example) code, tried with others too...</sub></p>

<p>It seems your AVR is not updated, try to update your <code>Arduino Avr Bords</code> on the boards manager. also make sure your <code>avrdude.conf</code> file might to be :   </p>

<p>Dont forget to wire RX to GND or connected RX to TX directly.</p>

<p>Hope this helps.</p>
 48726: <p>When soldering the pin headers, I used too much flux. So this caused contact between the GND and RST on the ICSP causing the arduino to stay in the reset position. I removed the ICSP pin headers and there was a lot of flux. I removed it and now my arduino is working perfectly. Thanks to @Juraj for figuring it out that there must be a contact between GND and RST</p>
