I have installed windows 7 and love it but somehow my system wakes up from the sleep by itself? It is very annoying. Please let me know how to solve it.?

Here are some details on what you should check to fix Windows 7 sleep from waking up automatically.
It may be due to your network card. You have to prevent your Network Card to wake your Windows 7 up from its sleep
My computer->Properties-->Device manager-->Rt click on your network card -->select properties--> Power Management tab-->Uncheck the option “allow this device to wake up the computer”
