You may want to check the motherboard for capacitor distention / swelling as this is sometimes the case of this error. you also will want to check the computer usb ports to make sure that no damage exists as a shorted usb port will put the computer in a no POST mode. (Black screen only after dell logo splash) If the computer makes it past post try running the diagnostics from the bios. post your results here and I'll see how i can help.
