so this made me suspect of the vram power supply but in +FBVDDQ wich is the power supply i´ve got 1.2v so i think its ok
for the gpu power supply i got 0.7 volts and the chip gets warmer
so its the gpu chip died or the problem lies on one of the vrams?
should i suspect of the vbios
any reply will be usefull

thanks
