Dell / Optiplex 3010

Specs: Windows 7, intel core i5-2400s 2.50GHz/6 gigs
So I recently purchased a piece of 8 GB ram and was looking to upgrade my computers Ram. I already have 6 GB of ram inside in the form of a GB and GB stick. I switched the GB stick with the GB stick to try and make it a total of 12, but once I did that my computer wouldn't fully turn on constantly booting up but nothing showing up on the monitor. while the fans are my graphics card and all of the ports don't work besides the power cable. Does anyone know what is causing this issue? ( I also tried putting the original 6 GB of ram back into its place to no avail)

The Dell Optiplex 3010 accepts a max of 8GB RAM (2x4GB).

The maximum size for your comp is 8gb ( refer your manual )
Put the 6gb back in ( try both slots ) & boot into the bios.
What does it show?

Once in BIOS, reset to defaults, save and exit. In general defaults are a starting point and often not perfect but with a factory machine, it should be just fine.

You have to be a little bit crazy to keep you from going insane.

So I turned it on and tried to use the keyboard, but the keyboard is plugged in and not turning on. I also just noticed my graphics card isn't on since the fan is not moving and I don't know if that is important. I have tried plugging the keyboard in the front and back.

If you can't get a display on the screen, you can't change the BIOS settings. If you didn't mess with the settings before chaning the RAM, there's no reason to mess with them now. I'm guessing you either knocked the graphics card loose or you're not fully seating the RAM in its slots. Are there any beeps or LEDs when you try to boot up? If there is, that's a code telling you what the issue is. Find your tower on this list of diagnostic codes:

If you are still having difficulty getting the computer to work with the original RAM it can often be caused by oxide on the edge connectors becoming disturbed. Power off, clean the edge connecters of the original RAM with a soft pencil eraser. Insert each stick and remove it a couple of times to clean the each edge connectors too.

Always pop back and let us know the outcome - thanks

Riider so I booted up my computer and the LEDs did flash on the power button is red or orange(kinda color blind sorry) but the 3 and 4 LEDs are lit up red(or orange). It said that it was a memory module issue. It told me to put them back one in and restart it which I did but still nothing happened. I also took my graphics card out and the RAM to clean it with the soft pencil, but the 3 and 4 on the LEDs are still lit up even after that. The graphics card is also not apparently on since the fan isn't moving and the ports still are not on.

The code was if the 3 and 4 LEDs are lit up and the button is lit up red saying Memory modules are detected, but a memory power failure has occurred. It is in the 2009-2012 series

Be sure to use the original 2 sticks, at least for now. You didn't state which graphics card you have but if the fan's not spinning, you either didn't fully seat it in the slot, or you forgot to connect the aux power plug.

EDIT: Be sure to have the main power cord unplugged when working inside the case. And lay it on its side so you can exert enough downward pressure for the cards to snap in place.

Riider my graphics card is a MSI Radeon R7 250 DirectX 12 R7 250 2GD3 OC 2GB 128-Bit DDR3 PCI Express 3.0 HDC.

and yea I have used the 2 original sticks in there and the graphics card just has to be plugged into the slot, but it still does not seem to run.

while checking that the original sticks and graphics were put in all the way it still would not really turn on at all.

I forgot to mention that beforehand I disconnected the motherboard from everything and replugged it all back in to see if that would help which it did not.

I can't really tell how to fix this because I have tried cleaning the sticks and graphics card and cleaning the slots, but nothing happens.

Test with the graphics card out & use the onboard connection.

JohnW I still can't get into the Setup /Bios since The screen still stays off, maybe I messed up a wire or broke something I can't really tell what to do since I tried what the Manuel said and it still does not work either, I think I may be doing something wrong, but I don't know what.

I don't know why you would disconnect/reconnect everything but being that you did, did you mess with the CPU cooler?

Riider I'm not really good with computers so I thought that maybe it was a loose plug and thought it would help. I left the CPU cooler alone , it still runs.
