I am just trying to print "hello world" in the serial monitor and it display blank page.
I have tried the "blink" example also. It also shows blank page. And the board i use is uno 3
Your screenshots show "done compiling" not "done uploading": you need to hit the upload arrow next to the compile tick in the IDE>
(And the blink example has no code to make it print anyway.)

Still nothing
Yeah well this time, you have no Serial.begin....
well yesterday i installed my window 10 again for some reasons. Now i install andruino again.
Now compilation is ok
But problem in uploading
and my serial monitor is not opening now.
One screenshot shows a Uno on COM3, the other shows you trying to upload a sketch to a board on COM1. Do you see any problem there? Try Tools/Port.
Steve
i do think that as a problem. But wat to do ? i simply install the uno software . On the driver it shows com3. But error message is of com1.
Did you try going into Tools then Port in the IDE and selecting the correct port?
Steve
You need to select the Port in tools -> port -> COM3
watch the hello world and installlation for more info
in Tools-> port-> there is only one port that is com3
BUt error window shows error of com1
In my IDE it says which board and which COM port in the right bottom corner. That should state COM3. If not, you did not select the port.
If you remove the Uno, is there any change in the ports menu and in the Windows device manager?
