BSOD followed by white dots/ lines when restarted.. Need help

Recently my computer started getting BSOD and then shutting down when playing a game. Yesterday that happened aswell but now when it starts up it goes in to some state where its white dots and lines all over the screen. Im wondering if its hardware-related and what i can to do fix it(start playing games again)?!

Setup:
Graphics: Geforce 9800 GT
Motherboard: Asus M5A78I-M LE
Processor: AMD Athlon II X3 455 Processor 3,30 GHz
4 G RAM

I am running Windows 7 Ultimate 64-bit.
I have reinstalled Windows, checked the RAM for bad memory spots and the hard drive for bad sectors using Windows 7 tools without any results.

I have attached how it looks like after the restart plus the minidump files.

Edit: I recently updated my Graphics card to the latest version, and the BSOD has happened afterwards. I formatted the PC but to no avail though.

Any help or advice would be much appreciated(note that i am an amateur).
