Nah, it's temp was moving around 48-52°C,and the ventillators are spinning really slowly, so that woudln't be a problem.
Somebody from another site said that it is caused by a messed up vga memory, but I won't run tests for that, I guess I wouldn't be able to repair it, and it would get messed up more than it is now.
But I guess what is the problem, I let the "SmartDoctor" set the clock rate, and it might f***ed it up.
I won't let it do that again, or I won't even install it.
By the way, I reinstalled windows, and found out that it is not a software problem(aww no shit), and Ill take the card back to the shop today, thanks god it has warranty(it is a brand new card).
Thanks for the help though.
Closing.
