System does not boot

I was having a dell dimension machine problem, this machine cannot boot, when pressing power switch on, there was no sign on the screen, I attempt to solve the problem by reseating the RAM, then the battery but still not work.
Please people is there any way to solve this problem?

You'll probably have to order the correct one from DELL.

but here's a few things to try.

Test the Power Outlet or Power/Board by plugging in a radio or lamp.

Try another Power cord/lead if you have one.

Remove the Power cord from the PSU to discharge the Capacitors in the Power Supply. Then press the Power button for 10 seconds to discharge the Capacitors on the Motherboard. See if it will start. If it does start you can replace the (PSU) Power Supply Unit as it is faulty.

Swap the Reset connector on the Motherboard to the Power connector to rule out a faulty Power switch.

Remove the Power lead from the PSU, disconnect the 20-24 pin power connector from the motherboard. Reinsert the 20-24 pin power connector to the motherboard.

Swap the Power Supply unit for a known working unit if one is accessable.

Check the Capacitors around the CPU for swelling or bulging. They should have a flat head with a cross indent.

Clean the golden edge of each memory stick with a soft rubber/eraser, remembering not to touch the golden edge of the memory stick. Check with one stick at a time, remembering to disconnect the power from the PC.

Remove and clean the Video card with a soft rubber/eraser and then reseat it.

Remove all Add on Cards and see if it will start. Clean the add on cards before reinserting them one at a time and testing.

Faulty Fans, Dust and Grime build up on the Heatsink restricting air flow. I would give the inside of the case a blowout with compressed air. When blowing air through the fans make sure that you physically stop them from spinning, as they may generate power and **** something up. Remembering to ground yourself by placing the back of your hand on the Power Supply Unit and not moving your feet. By not taking this precaution it is possible that you could inadvertantly cause damage to the PC from an electrostatic discharge. Then remove the Heatsink, giving it a thorough clean and reseat the CPU applying new CPU grease. If the Fans spin freely when you give them a spin they are probably OK. If there is resistance replace them.
