Zotac GTX 960 - dwm.exe crashed with nvidia driver, board burnt on 12V filtering inductors
Hi guys!
I just had to troubleshoot my brother's GTX 960 GPU that's faulty, running Roblox and PCSX2 for about 5 to 7 mins in the game, and bamm! the display goes black :(
Also, when the display cuts off, i heard the HDD are going spin down and spinup again, windows still loads.. still wont display until forced restart by long pressing the power button.
Checked event viewer and reliability monitor, has dwm.exe crashed along with the NVIDIA driver.
i have swap the motherboard and playing with memory sticks frequency, but with the same GPU and still does it. Lastly, i tried different PSU (from MSI A550BN to Corsair HX1000i), comes to pressing the power button, and what i got here... the GPU getting burnt 😭😭😭
for more context: this GPU initially still displays normally, but at random times it crashed the dwm when still using the 550W PSU, but blow up when using the 1000W PSU.. is this a GPU problem or the PSU too big for the GPU?
thanks to that OCP kicked in, other PC components are still safe!
what getting smoked is rows of filtering inductors on 12V PCIe power input. checked the resistance to ground, got 37 ohms (very low). all rails (PEX, 5V, 3.3V, and 12V PCIe slot input) seems normal, and has high k-ohms ratings, i also checks the memory MOSFET, got 45 ohms, and NVVDD (core) is on 7 ohms..
does this card still have chance to live again? thanks!
