Look at the motherboard (mobo). Failure of motherboards is usually due to breaking capacitors. A few years ago a capacitor company stole the "recipe" for making capacitors from another company and tried to make their own, unfortunately they did not get the ingredients right and the capacitors started breaking after 2-3 years of use. They sold these capacitors at very cheap prices and a lot of computer companies and power supply makers bought them. This is easy to diagnose. Look for capacitors (caps) (they look like little tiny soda cans) on your motherboard (mobo). They should be perfectly flat on top and not bulged or swelling or leaking anything.
You could also try to change out the power supply if you can find another one that fits it.

Try this: remove the DMOS battery and unplug the on/off switch plug. It's the one in the corner near the power supply. To be sure follow the cable from the front on/off switch board on back to this plug. Then plug the A/C cord in, if the system boots up fine, then replace the front panel power on/off swith board. Naturally you will not be able to power off the computer using the power switch (since we unplugged it), so you will have to just pull the plug. Hope this helps. Joe

this logo with the dell picture can be disabled from the Bios settings ..to get there press F2 on start ..or what ever key is indicated on that logo screen for to go in set-up ..and in there under advanced settings look for screen logo ..and disable it ..after that f10 to save settings ..or in some bios editions it will ask if you want to save changes on exit ..select save changes and exit ..
just look carefully in the tabs ..cause this option is there for sure..and disabling the logo will kinda make it boot faster ..
