It gives me this error msg

When I go to device manager, it tells me Arduino Uno R3 (COM8), so I dont know what to do. Please help me out !


Try simple first.
Unplug the Arduino
Reboot the computer
Plug in the Arduino
Start the Arduino IDE

Sometimes windows serial port handling can get flaky.
Avoid throwing electronics out as you or someone else might need them for parts or use.
Solid state rectifiers are the only REAL rectifiers.
Resistors for LEDS!


Well, if you are able to upload something sometimes, I suggest you to test http://arduino.cc/forum/index.php/topic,118440.0.html because the "wrapper" in avrdude will attempt to 'disable/reenable' the plugged arduinos on failure.

Otherwise, smeezekitty solution is the way to go first.
