Hi, I need some help. My HP G60-635DX Laptop is getting a continuous beep on startup. The computer boots but it takes a while, and the beep doesn't stop until the windows flag starts showing on the screen. When the computer gets to the desktop, the mouse jumps around, like when I click on My Computer, it opens something totally different. Also, when it starts, the hard drive LED on the front is blinking in time with the beeps. Can anyone help me fix this? It happened once before and HP got it to stop but now it's back and they won't help me!
