Graphics card Artifacts and BSOD error

Hello,

Yesterday I booted my computer up and started browsing the internet, after half an hour I got a warning telling me that the video card had crashed but managed to recover. A while past before the screen flickered black and came up with a blue screen of death, with the following errors:

Stop: 0x00000116

nvlddmkm.SYS

And that was it, after I rebooted it. The BIOS had red artifact going horizontal lay along the screen, the artifacts disappeared when I got to the windows 7 loading screen, I then did research on the error for possible fixes. Although any of the solutions I came up with, did not work. I have got to the point where I went into safe mode, uninstalled the driver and revolted. Then installed it again and when it restarted. It worked, but the same bsod occurd. After trying this twice and other things, such as scanning for virus and also doing a clean boot. The computer can't even see the card.

This happened some to ago and one of my friends fixed it completely, I never thought of asking what he did. So now I am complelty stuck, with a computer that is able to boot up, but has limes going down the screen and is in 12-bit colour mode because it can't find the graphics card anymore.

Any help will be hugely appreciated.

(Sorry for any typos, currently using my tablet)
