So let me explain, I bought this off https://bit.ly/3WhMdbo (yes it is shortened), so I when I cleared my ram, it kinda worked, but when I unplugged it before shutting down my pc, it stopped working, it worked again once when I install ch341 but didnt afterwards, it also worked when I tried to download it's drivers by going to hardware ids, but didn't later. Please give me a solution.
I'm a beginner
Model: Arduino R3

Please don't; a lot of people are reluctant to open an unknown URL.
What does that mean? PC RAM? Arduino RAM? What exactly did you do.
Vague, very vague. Please provide the details.
If you remove the power, it will indeed stop working.
Coincedence. If your board indeed has the 16U2 (and it looks like it), installing CH34x driver will not help.
I once removed my ram and sticked it back in, when done it worked but after I unplugged it, and replugged it, it wasn't getting recognized
Answer to 2. It was just a circuit, I do not remember but it didn't cause any problems to the board, it was a blinking led circuit,
3. The RX light is blinking
There is no RAM chip on an Arduino Uno R3 so you must have removed the RAM on the PC and re-inserted it. Double check that it's properly seated.
Far too vague; you might have made a mistake and damaged something.
No, COM3 doesnt disappear, it's still there, The IDS for the COM is USB\VID_2341&PID_0043&REV_0841
and
USB\VID_2341&PID_0043
The circuit is a blinking led example project in the IDE
/*
BlinkTurns an LED on for one second, then off for one second, repeatedly.
Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO
it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to
the correct LED pin independent of which board is used.
If you want to know what pin the on-board LED is connected to on your Arduino
model, check the Technical Specs of your board at:

*/// the setup function runs once when you press reset or power the board
void setup() {
// initialize digital pin LED_BUILTIN as an output.
pinMode(LED_BUILTIN, OUTPUT);
}// the loop function runs over and over again forever
void loop() {
digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}
The cathode was connected to pin 7, and anode was connected to 5v with a 10k resistor
Hope, this information could help?
So COM3 is not the Uno.
OK, that would be a 16U2. I would suggest to try Atmel Flip to revive the 16U2; There are instructions on the web, I've never used it so can't advise.
OK, that should not be the cause of the problem.
The COM 3 has the UNO R3 just for correction.
I have windows 11, also.
Did you try to run it? The information that you showed might be from before Windows 11 started its life.
It worked, I didn't even put it to DFU
It indicates the 3rd party manufacturer of this clone board failed to install the firmware on the ATmega16U2 chip before shipping it to you.
