I've been trying to turn on my laptop and try log on the users thingy, and i wait for a while to see if it logs on, but it doesn't. when its logging in it just freezes, i turn it on and off a few times but it doesn't work. i don't know it i have to remove the memory from the hardware or if open up my laptop, i don't know what to do? PLEASE HELP ME!!!!!!!!!!!
