Problems with serial communication on Arduino UNO R3

Trying this on a Windows 7 64 Bit machine. First i plugged in the Arduino board to the PC with a usb cable. This gives me a steady light from the L and ON LEDs.

Windows began installing some drivers automaticly. When done i checked the device manager and noticed the device was recognized as "USB-SERIAL CH340 (COM3)" and windows states "This device is working properly."

Then i ran the Arduino IDE. Selected Files->Examples->01.Basics->Blink. Checked Tools->Board->Arduino UNO and Tools->Port->COM3.

If i then compile and upload i get the following message after a long wait period:

Problem uploading to board.  See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0xc1

At this point i have tried an older version of the Arduino software. Two other PC's (one of them running Win10) and i did a loopback test but nothing is working.. The lights ON and L are always lit continously when the USB cable is plugged in. TX light never even blinks or anything. Also should i be able to use the reset button ? It does nothing at all .. I would think that i would at least be able to see the LEDs flash or something ?

It seems a driver problem dude. Try uninstalling the drivers and then installing from the "C:/ programs data / arduino / drivers" (or whatever you have installed the program) I'm a linux user sorry for that path. – ElTête
Already tried that. Windows tells me that there are no suitable drivers in there – Daniel Jørgensen

Take a look at this: http://www.arduino.cc/en/Guide/windows#toc4 The fact that your Arduino shows up as USB-SERIAL CH340 is probably a sign that you haven't installed the proper drivers.
