Hi all, I have a GTX1070 that stopped working all of a sudden. My PC lost power all of a sudden and would not power back on unless I remove the 1070 from the machine.
I did some digging and I found the bottom VRM (4C85N) to be shorted on the top FET. The bottom FET appears to be ok. I replaced the VRM but as soon as I power on my PC the VRM gets shorted out instantly. I have tried replacing it twice but I get the same result each time. I don't have enough know how to troubleshoot this and am looking for input to try and figure what the cause is. The card will boot/power on with the VRM/phase removed. See attached picture of the VRM in question.
The next step I thought of trying was to replace the driver but the marking on the chip "02=3C147" can't be found when googling.
Thanks in advance.
