Gaming computer slow, Not sure why

[someairforceguy]

So I recently bought a bunch of computer parts from new egg.(Will list ALL COMPONENTS AT THE BOTTOM OF THE PAGE.) Installed them all (with little to no help from the manuals that came with the products) and booted up the computer. In the ATX slot, it requires a 8 pin adapter for power, I did not have an 8, so I used 2 four pin slots. The diagram of the ATX rail has slots on the end that are unique, I figured a 2x6 wouldnt meet the criteria so again used the 2 four pin slots from the psu.

MY next concern was the 2 blue screens I got after windows loaded (it was installing windows updates when it happened) Right after startup it went blue screen and did a memory dump, then reset and was fine. No more blue screens.

My OTHER concern is that the memory is WAY too slow, I bought corsair vengence 1600s 4x4gigs and i believe its running at an extremely low frequency..Not sure how to check it or alter it.

Next, my OS is 64 bit, and Im currently at 32 bit (have an outdated monitor) and cant seem to go any higher from the desktop settings.

Also, when I was first attempting to download items from webpages, it wouldnt register for minutes. I would click the download link, and no response. Eventually it would load and i had it pop up like 5 times in the download manager, but im not sure why the delay. I have installed direct x11, flash, adobe and all other updates and it still would load sluggishly..Not the internet connection. After I went into admin settings under user accounts, i disabled the notify option for programs...Seemed to help because I couldnt even download to the hard drive without getting the message "ACCESS DENIED" I am the only user on this computer, and the admin, yet for some reason windows wouldnt let me do anything until I selected the DO NOT NOTIFY ME option in the user account settings. Weird..

So far the maintenance Ive done on this computer is install drivers. Did a clean install of windows 7, installed the mobo using the disk provided with it, upgraded bios (using the mobo utilities app), downloaded more drivers for the graphics card from nvidia, and installed all the windows 7 updates.

The graphics card sucks. So if you can return/sell it and get a 580 or even better, a 590. All your other components are great.

You need windows ultimate to take advantage of your RAM, its not showing up as 16 because windows home doesn't support that much memory, which is another reason why your computer is showing as x32.

The monitor may also be another reason, if it has a really slow response time, however it wont affect your RAM or anything as it is just an output device.

Windows 7 Home Premium x64 is enough, do not need Windows 7 Ultimate x64
