well..

first.. i wanna say.. your psu is crap..

your card is dying because of psu fault..
in other word..
your psu has destroy the card..

codegen psu can only deliver around 50% of their wattage label..
more than that, well, crazy voltage fluctuation and ripple..

maybe no...

lines and squares on your screen, known as "gpu artifact", mostly because of your graphics faulty hardware.
changing your psu will not recover it to early condition...
it has already broken..:|

the only thing that you can do is throw your codegen psu, buy the tough one, and buy new graphics card..
