PLEASE HELP! Beeping and black screen when laptop turned on
OK, I've had this laptop (HP pavilion dv2000) for a while now, and I have no idea what happened. Recently, when I turn it on, all the lights turn on—but after around 5 seconds, it beeps loudly four times. Also, the screen is completely black—nothing pops up. The black screen goes on forever. If anybody has had this problem or knows how to fix it, I would be extremely grateful for your help with this problem. I have no idea what to do. Thanks.
