L light flashes on Arduino Mega 2560

Hello.
So my board has just arrived and i plugged it in,the on and l light turned on and the L one flashed.
Windows tried to install drivers for it but then it said it failed.
I tried on 2 computers.
Nothing.
Same thing.

What could be the problem?

What could be the problem?

Start here

Never mind.I found the solution.
Finally.
Since I know how it feels to google around and not find an answer in the topic.

Here is the nice tutorial that i found.
So others who have same problem don't come across a topic with a problem and then a reply saying,Never mind i got it and no solution.
Long story short,I never knew a Windows is supposed to fail in driver installation.

Oddly enough, it is all in the instructions here, which follows on from the link I posted earlier.
