Issue with 64 bit amd/windows 7 forms.dll? SFC /scannow failure

I was having computer issues after a faulty driver install. So to make it easy on myself, I decided to do a full reformat and re-install of Windows 7. Got everything up to date, service pack 1 installed as well as the other windows updates.

But my computer keeps freezing throughout the night, or windows suddenly crashes and causes a reboot with the message that it did not shut down properly.

So I did memtest, fine. Dskchk turned out fine as well.

Then I ran SFC /scannow from an elevated command prompt.

It gives me an error stating that problems were found that it could not repair.

This is my sfcdetails.txt contents:

Long time visitor and you guys have helped me solve issues before, this is my first time posting though so you know I'm stumped.

Perhaps one of you true genius types might know more. Thanks in advance, and hello.

Edit: Hardware specs in case they are needed:
Asus M4A79XTD EVO
MSI Twin Frozr Geforce GTX 560 Ti
AMD Athlon Phenom II X4 965 processor 3.4GHZ quad core
Ripjaw 8GB PC10333 ram
2x Western Digital 1TB hard drives
USB Netgear n600 DB wireless network adapter
Merc Stealth Gaming keyboard
Logitech G5 gaming mouse
Samsung 24" Syncmaster P2450

Try running it several times it can't fix them all at once. Also you can replace system files from your installation dvd but since you have installed sp1 it would have to be one that has sp1 already slipstream or is bought that way. You also have to take ownership of the files that you would be replacing.

You can make one via this tutorial:
