Thanks Jose , i found that before but there is no solution there :(
Try testing one DIMM at a time. One slot at a time. This will help weed out the bad RAM or slot.
thanks again for you're reply, gonna try it tommorow, i'll let you know if it solved the problem
no bad RAM or slot, just a lot of dist, it's fixed now, thank you for you're time and help !!

You may have a failed motherboard then. 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. Make sure you look at all of them, on DELL's especially look under the cooling fan shroud as well. The dead giveaway is the fact that you are not getting anything after you changed the PSU. There are a few companies that will repair broken capacitor issues. Also if you add a bunch of extra components without upgrading the power supply you can suffer underpowered situations and that can cause internal parts to fail.
To eliminate some other stuff you could remove the memory and disconnect all the power plugs from the drives and then try to start it up. If it does not change the behavior at all (no beeps, no change in flashing lights) then you probably have motherboard issues. Make sure when disconnecting the memory chips (sticks) that you touch the metal on the inside of the case first to discharge static electricity. If it does change the behavior add 1 component or item back at a time to see what you can find out. Post back with what you find. And remember a bad PSU does not mean no power, just not enough to run the computer. Is the PSU that you replaced the same or greater output watts?

As you can imagine, this is not simple thing to diagnose.
First, we need to try Dell's steps to fix...
Remove non-essential peripherals…
Except for the monitor, keyboard, and mouse, remove all external peripherals including:

Try rebooting. If that doesn’t work, Dell states you need to do the next step.
Remove and Reseat Basic Hardware items:
At this point, Dells says if that fails contact them.
If my hunch is correct, you may have something on the motherboard shorting a connection or you have a blown capacitor. Get some “canned air” and blow out the computer thoroughly. Some people have reported the same symptom having dust or other debris causing the issue, so give it a good blowing out,
At the same time, inspect your motherboard thoroughly for an anomalies. If you see anything resembling the picture below, you have a serious motherboard problem which will require replacement.

First check your power supply at the outlet. If that is okay, check that the power is turned on at the back of the cpu. If still no power check the power cord. This part should be easy since you have a computer that still works. Just switch the power cords. It does sound odd since all three stopped at the same time. But if they all run off the same circuit you could have a bad fuse or tripped breaker.

You need to have the Power Supply replaced on your Dell. Don't even think about repairing a power supply it caries dangerous voltages and you can get seriously injured. So just take the Dell to a Certified A + Technician Shop near where you live Local shops will often work with you if you do upgrades and repairs with them Good Luck! If you fel you can do this repair be sure to ground yourself so you dont short out your Motherboard components. and remove tyehb screws from the power supply and detach the power cables from the motherboard and hard drive and other drives optical drives CDRWs then replace and reconnect the new power supply dont buy the cheapest one getb a power supply rated higher than yoiur current one so that when you upgrade the system there is enough power there to run all the drives and devices. Good Luck Write me if you have questions I am a A+ Certified Technician with 14 years experience and I have a part time Computer Business. I had a Retail Computer Store and Repair business for over 8 years in St Petersburg ,Fl I do part-time repairs and upgrades now as well as new custom builds by request.

Try to clean the RAM and place it again in the motherboard.
