    Gigabyte GTX770 repair attempt

    Hi folks, a GPU repair newbie here, kindly asking for a help with my GTX770,

    - the PCI 12 and 3V (kOhms to GND) as well as VCORE (~ 25 Ohms to GND, maybe too low?) seems OK
    - there is a short (<1 Ohm to GND) in bottom-right section of the card (see image), both the inductor and capacitors around.

    What is this powerline? 5V, PEX?
    Can I just inject voltage, say 1V?
    Or is it one of the mosfets? Can I test them in circuit?

    Thanks for your tips, JP

    Test mosfets in circuit: red probe on ground and black probe on pins !

      GIGABYTE GA-H110M-S2 - Stuck at Debug Code C2 - don't like Patriot Viper Steel RAM but works with G.SKILL
      by DynaxSC
      Hi,

      I discovered a strange behaviour of GIGABYTE GA-H110M-S2 board.

      General test conditions:
      - Tested with Core i5 6500 and Core I7 6700K - no difference
      - Default BIOS settings, but tried also altering several memory setting - does not change anything

      What is wrong:

      With BIOS F1 and F2 the board normally POST's and boots to Windows 11 with 2 x Patriot Viper Steel PVS416G440C9K RAM (4400MHZ, Samsung B-Die chips)

      When BIOS upgraded to anything above F2 (ie. F20-F27b) the board POST stucks after 3 Debug Codes on Code C2

      A Dead/DOA Gigabyte GP-P450b 450W ATX PSU
      by momaka
      More eBay specials: this time a Gigabyte GP-P450b 450W ATX PSU for $8 with free S&H. Listed “For part/not working”, as usual. Showed up in a beat up EVGA box without any padding… but that's understandable given the total price. PSU made it out fine without damage. It's a non-modular (yay!), pretty modern-day looking PSU with a black paint and all black cables (meh, not my favorite, but figure it's good to keep a few of these in case I do need one for a more modern PC build, just so my old gray boxes don't look too odd in there.)
