Inspiron 3847 powers on, then off immediately
My Inspiron 3847 turns on, but just for an instant. Tried a new power supply. No luck.

Sure the new PSU works? Does the power button light up and what color, steady or blinking?
Have you tried disconnecting everything except mouse, monitor and keyboard?
Disconnect PC from the wall, and visually inspect all USB ports for damage. A shorted USB port can cause these symptoms. If you find a damaged port, you could try using something NON-metal to gently separate the contacts, but that port may never work again.
If that doesn't help, you may have to strip the PC down to bare essentials by removing all PCI-e cards, except video, all RAM modules, except the one in slot 1, disconnecting all drives, except boot hard drive and then see if it boots with only mouse, monitor and keyboard connected...
