Dell inspiron N5010 making 8 beep with no display
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.
