can you get into the bios? hit the F2 or EL keys when you start it up

If all you get is the power light, no fan, no drive sounds, system had hardware issues. Try to run it without the battery. If that does not help, reset the BIOS (will need to take out the BIOS battery for a few seconds inside the case).

Have you tried an external monitor just to rule out a bad screen?

Next step is to try new RAM. If that did not help, you are looking at a system board replacement. If the laptop is old probably not worth the labor and part costs.

the fan runs and there is dvd rom noise.the lights stay on for a bit then go off then back on.it repeats those steps. could i try an external hard drive to see what happens.

BIOS battery is inside, usually under the palmrest or the keyboard. Have you tried it without the main battery also?

From the sound of things, if an external monitor got no image, your system board went bad. A BIOS reset may help, but it's not a great chance.
