This is my case:

Ill be fine with the cooler you told me about?

actually im looking at  Coolermaster Hyper 212+ which you mentioned first. 30 bucks seems resonable.

Def going for ram upgrade and CPU cooler. Dont know where to begin for the CPU cooler as I never done this before. Any advice for coolers?

thanks for your reply. I plan on using this computer to make youtube videos, image editing, and websites. Do you still recommend my video card to be updated? If so I may need you to point me in the right direction since I have been out of the loop for a while now. Last time i was involved the 8800 was a great card!

And......

In this situation would you still say a ram upgrade is unnecessary?

I have an old gaming rig that is starting to show its age:

---------------------------------------------------

4GB of Corsair DDR3

AMD Phenom II Black Edition X4 955

Corsair 550Watt PSU

Nvidia N250GTS

----------------------------------------------------

My first main concern is the extremley loud noise my computer makes(for as long as I remember) when running, sounds like it could be comming from the CPU. 

My second main concern is wondering if my Power Supply has enough power to handle a 4GB ram upgrade and a new cooler for my CPU.

My CPU has a stock cooler on it. But I feel I need better cooler since my computer sounds like an aircraft!

Does you guys have any advice on these manners?

Thanks in advance!

I wana keep the 500 GB for windows. Its recommaded to install another OS on a new drive. Not only that but I dont understand how tro partition and dont wana mess anything up. I would rather a new drive.

Its been a while since I messed around with my computer but does anyone have any advice on buying a new HDD. I dont need anything facy, I will be installing another operating system on it. I mean I have a 500GB HDD now with windows 7 on it and I dont see myself having a issues with the size. But yea, if you have any advice please let me know.
