Error installing OS on fresh new computer (0x80070570)

I just received my new computer parts. Me being pretty much a newbie when it comes to computers, I got some help from two friends to build it.

Now, when I want to install my OS (win7 home premium 64 bit - CD bought from store) on my SSD, I get the error 0x80070570 - corrupt files during the "Expanding Window files" process. I have used that CD to install on my previous PC with no problem.

Thinking the CD was the problem, I downloaded a ISO and burned it with PowerISO. Tried installing and same problem happens.

Reading on the internet from multiple forums, some mentioned trying with a 2gb ram stick only. Not having a 2gb stick, i still tried removing one of them (4gb sticks).

Doing that i managed to complete installation until the "Completing..." part of the install, at which step computer crashed with a BSOD.

Here is a summary of things I have tried:
-2 different ISO
-Installing on my HDD
-Clearing CMOS
-Restoring BIOS to default
-Trying 1 stick of RAM (4gb)
-Transferring SSD on working computer, installed Windows, then transferred to new computer using Sysprep

Nothing of those helped me.

Recently I Flashed my BIOS with the most recent update (Z68BFC15.BST). I managed to install windows and drivers, but when i add my 2nd stick of RAM (total 8gb) computer won't boot (BSOD at windows loading page).

Is it hardware problems? If so how can i know which part is causing it?

Thanks all for the help

Where did you get Win7? Burn the ISO to DVD using ImgBurn at 4x speed. Clean Install Windows 7

-Update-

After updating my BIOS, I managed to install windows, but still with only 1 stick of RAM. I have tried all 4 SLOTS with my 2 sticks of RAM and no problem as long as there is only one at a time. When 2 sticks are together in the red sockets (16x) or in the white sockets (8x i think), I get a blank screen when loading up windows. My motherboard specifies that it can take up to 32GB RAM.
