when i turn on my dell laptop it shows a blank screen and when i hit the f8 button i only get a beep sound.i have tried shutting down and removing the battery but same problem persists..please help!!!
This beeping sound that you hear might be due to either failing mother board, RAM or hard drive. Depending of your motherboard manufacturer, you can find what this error means.
Can you hear the drive spinning up? If can't then the hard drive has failed and that's the reason for your system not to start up. You could try pulling out the drive and connecting it to another PC via SATA-USB cable to see if it will work there. If you have an external enclosure, you could try with it.
Another option is to test your RAM for failures.
