Hi
Things you can try out:
Take out battery leave it out, push the power on button for 30 sec, put the battery back in and turn on.
Take out battery leave it out, use the charger for your notebook, turn on.
Take out one RAM at the time to see if there is a faulty RAM you're dealing with
Take out the HDD and reconnect it.
If you can access your notebook after one of these tries, update your hardware (Atheros WiFi card, Intel Chipset, ATI/nvidia graphic driver).
How old is your notebook, and also which version of your notebook do you have? (Ja, Jq, Jv)
