Computer Freeze only in Games please Help, no error

Ok so here is the result of furmark3: freeze after 49.43 mins
The benchmark was running on 14-15fps

Do you have any other graphics cards you can test? Or do you have any other PCs you can test your graphics card on?

ok then it is the grapicscard have changed it with an old gtx 260 and then it works fine but slow xD
Would it help if ill oc the card a bit or do i make it worse?

Well I wouldn't overclock it that much as it can cause problems.
I would recommend buying a new powerful, I understand that they are a lot of money though.
It looks like your problem has been solved though so can you please mark the thread as solved.

ok then im going to buy a zotac 770 4gb

thank you for your help and support and having that patience with me =)

No problem, any other issues feel free to let me know.
