Arduino STILL gives me errors

Ive had a Arduino Uno for 2 and a half weeks now and since yesterday, i couldnt program,

It gives me this error

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

I have SEARCHED AND SEARCHED the internet many many times

Here are some details
*Computer recognizes the port
*I can see the Arduino board in device manager
*It compiles in a few seconds
*After 3 minutes of uploading, it displays the error
*The (ON) and(L) were always on since i started getting errors
*When I hold or press or do anything with the reset button, nothing happens
*There is no error with the CH340g
*Loop back test didnt work
*Nothing plugged into TX or RX
*I have deleted and reinstalled the IDE
*I get the same error in all versions

Help me ASAP

I get the same error.

I am using Arduino Uno
Operating system is Windows 10
CH340g USB to seriel

Link to Supplier

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

Double-check that you have the correct port selected in the IDE, under ">Tools >Port".
(I can reproduce your error by selecting the PC's normal serial port in the IDE, instead of the one with an Arduino attached.)
