Also, I have a 64gb SSD that I've never installed into anything; a new 2TB 7200 HD, and a 750w aftermarket power supply, as well as a few older misc parts that are probably outdated.
Swapping out computer components of by itself is not complicated, however, you must take certain precautions to prevent ESD (electrical static discharge) from frying your computer components (new or old).
First, go to the computer store and by yourself one of those ESD straps. Usually most are less than $10.
Second, never, ever, work on carpeted surfaces when you are dealing with the insides of the computer. Your kitchen table or hardwood floor will suffice.
Swap ONE component at a time. Do not attempt to remove all components at once and they try to replace those back. Unless you have built over 1,000 computers like I have, this is the best method for someone who is inexperienced in computer component replacements.
This means... when you decide to replace that old power supply unit (PSU)... strap on that ESD strap, put the other end (the clip) to the computer case frame... usually on the bottom so that the strap cord doesn't get in the way.
Next, unplug the power cord that goes from the wall outlet to the power supply unit.
Yea, I know that should be fairly obvious, but trust me, I've seen clients that did not do that... they ended frying their computer because they left the power cord plugged in. Also, it's dangerous, too!!
Then... unplug all of the power plugs from each device that the power supply unit cabling is connected to... including the ones that are plugged into the motherboard, if necessary. Be mindful of each plug and where it goes. When you take out the old PSU and replace it with the new PSU, then reverse what you have just done with the old PSU. Make sure that ALL devices are plugged in, including any cabling that goes onto the motherboard, if necessary.
With all of the other components that you are planning to upgrade, the concept is the same... take your time and do not rush it. I have seen far too many screw-ups by clients who *thought* they knew what they were doing only to find out that was not the case.
Oh... just for the record... it would have not been necessary for you to put in all of the computer specs like you did in the 1st post.
All you had to do was give us the Service Tag number and we would have gotten all of the information from Dell's Support website.
Here's my suggested video card upgrade that should help you.
