My laptop will turn on, and I get lights on my keyboard, the lights above the number pad and on the left by my shift button flash on and off, but the screen is blank - no curser or mouse icon, just black. I downloaded the Windows Vista 64 Recovery Disk, inserted it and restarted my computer - still nothing. The laptop makes a sound like it's looking at the cd, but only in quick bursts. I have tried F12, F11 and F8 - nothing! My laptop is an HP Pavillion Vista 64. Please help. I don't know what to do now...
