My Dell Inspiron N5010 with 1GB ATI mobility Radeon Graphics card is making 8 beep sound repeadly with blank screen after stating it. I also attach an external monitor which is showing the display but there is displaying the Bluescreen error on that monitor and system is doing the on and off again and again. This bluescreen error also occured some days ago so many time but then i updated the graphics card driver and then the laptop start work well. After some days when i start my laptop and after entering the login password there is displaying blank screen, i tried so many time but every time after enter the password the screen was going blank. I needed to take up some important data so i run the system in SAFE MODE and take the data and shut down the system. Next time i start it again but this time no display and system is making 8 beep sound as i said initialy. Now i am confused where is the actual problem with the system part. Is it with Graphics card or its driver,with lcd or its cable or any other. I also disassembled my laptop completely. Now what should i do to solve out this problem. Plz Help me immediately.

ANKIT,8 Beeps is usually a LCD or cable failure. Try this first : “If the LCD on the system does not show any display, here are some basic steps that you can perform: Remove the battery and AC Adapter from the laptop and press the power button down for about 10-15 seconds to release flea power. Power up the system and then press the F12 key during the boot process to get to the Boot Menu, if you are able to see the display. It may be necessary to repeatedly press the key during the start-up process. Use the up and down arrow keys to select on the menu and press the Enter key. Or Hold down the Fn (function) key Power on the notebook You should then see the Dell logo screen with the message ‘Diagnostic boot selected’ in the top corner. You can then release the keys While the LCD BIST test runs, the LCD is operating on its own, free of the video controller, which may be discrete (a video card) or on board (on the system board). The test allows you to distinguish an LCD panel problem from a problem with the controller. If the colors are displayed across the screen without a problem, then the issue is not with the LCD.” from here. Hope this helps, good luck.
