Dell inspiron 8500 notebook monitor died

Your video card it bad. You will need to replace the motherboard in the computer to fix this.

Do you see anything on screen? Dell logo? I will assume you see nothing. Not even a Dell logo.

First test your power supply with a meter to be sure it is putting out 18-19 volts. If good, remove the laptop battery and try again. The next tests should be done with the battery not connected to the laptop.

Remove the hard drive and see if it boots. If not, next remove the dvd drive from the laptop and try to boot. If no good, remove the ram, clean the contacts on the ram and the slot with a pink pencil eraser....gently, just make them shiny. Try to boot with no ram/hdd/dvd. Put the ram back in and try again. Try connecting the laptop to an external monitor.

If after all this you still cannot get a Dell logo at boot time, the mainboard is likely dead. A refurbished one (with only 90 day warranty) will probably cost you at least $250 from Dell. Please let this one go and look at a new laptop.....sorry.

Hope this helps :)

it may come from viruses that attacked your comptr..in start up, pressing F8 to run safe mode n try to scan your compter using good anti virus software

is the crackling noise constant?
if so, your hard drive is lockup on the bootup. you have to get a new hard drive.
or you can try to reformat the hard drive, but I don't think that will help.

You should be left-clicking when the option for safe mode comes up...

with the external monitor attached press <FN><F8> to toggle between internal and external display. if still nothing then it sounds like the video card.
