Lines across screen during Windows booting then freeze

So this all started after the July windows update. My computer automatically installed
the update while I was at work. I came home to the BSOD, with the meassage PFN_LIST_CORRUPT.
I tried rebooting Windows and began having the problem with the lines start going
across the screen once the welcome to windows screen loads. Then when the desktop
shows on the screen it will freeze. (However, no issues when loading into safe mode)
(I also tried using System Restore)
After searching numerous forums it became clear that my RAM was supposedly corrupt.
I purchased and installed new RAM.
Again, upon loading windows, I received lines across the screen and then the freeze
when the desktop appears. This was followed by the monitor shutting down, then starting
back up with the BSOD again. However, this time it had the NV4_DISP message.
I researched this and found it to be an issue with my nvidia graphics card (FX
5200). I downloaded and installed new drivers (In safe mode). Rebooted and again
the same problem.
I have been searching, and cannot find any help with this. Can someone please
help!

Thanks in advance
