Dear Bad Caps,
Ive been trying to search extensively on how to diagnose a Bad GPU chip but cant find too much, I thought i might just tap into the wealth of experience here.
I have this GTX 550TI came with a short. I noticed that the Thermal paste was rock solid and took a lot of force to remove the heatsinks for both VRM and GPU.
Found that it was a mosfet blown in the main VRM to the gpu chip. Replaced that and found that a electrolytic cap was bad and was causing short. Replaced both parts and Tested again the short was gone so After Powering up and testing it turned on for a few seconds then tripped the psu short detection. the same mosfet was blown.
So ive removed all the high side and low side mosfets from that rail completely and tried to to test again, within seconds of turning it on the chip was blazing hot, burned my fingers twice. so i decided to put the heatsink back on and try again. It turned on again for a few seconds and it tripped again. Blew another short.
So my question is what could be causing this to keep happening? Is it a bad GPU chip?
Regards
Taxin
