Hi Peeps,
 
My trusty GTX 770 (2mb SC) has hit a snag. After being faithful since 2013, this is the first time it's ever had an issue.
 
I was playing Skyrim (no mods apart from SkyUI) the other night and the system froze. I could not ctrl-alt-del or alt-tab out in anyway, this was froze good. So I had no option but to power off and then power back on. On my machine restarting, i noticed the resolution was lower than its normal 1920x1080 so I checked device manager and it was displaying the dreaded Error Code 43.
 
I have since tried the following to resolve this issue:
 
* Remove all power and discharge from the machine for 24 hours.
* Remove GFX card and reseat. Also tried placing in other SLI slot (although i'm not using SLI)
* Clean contacts and checked power to card is still plugged in correctly
* Put in spare SSD and reload OS
* Update Motherboard Bios
* Update GFX card Bios (for the same bios in case it was corrupt or anything)
* All temperatures are around 40-50oC.
* Restored an earlier OS backup to original SSD.
* Uninstalled Nvidia drivers and also tried with DDU in safe mode.
 
Im pretty much out of ideas at this point. I think i've also worn google out from looking up alternative ideas.
 
Can anyone save me in my quest to revive my GTX 770?
 
Machine Specs:
 
ASUS Z87-Plus Motherboard
32gb Ram
Intel Corei7 4770k (not overclocked)
Windows 10 pro

    Sounds like the card may be suffering from solder cracking somewhere on the PCB, or it could be the power supply and you might try another one or try the card in another PC.

    You can disassemble the card and bake only the PCB like this (there's lots of other videos too) with the GPU side up which should reflow any solder cracking that might exist..Put it back together and hope for the best..That will hopefully fix for a while, or for a long time, who knows.
     
    I bake at 385F (about 200C) for ten minutes.

    Shot in the dark but try reflashing the firmware.

    Had the same issue with my GTX 760. When I installed drivers it would just crash or wouldn't go upto 1080p resolution. Went to local repair guy and he said driver chip needs to be replaced. Ever since then had no issues.

    I also have been suffering from this curse known as error 43, tried everything that was out there..re-installing drivers, use of ddu, uninstalling and re-installing gpu from the device manger. Also installed the oldest driver i could find that was no go as well. the card was working perfectly fine then i had taken like roughly 3 months break from gaming, when i powered on my computer i had frames dropping like hell. checked the manger and there it was with beautiful exclamation mark saying code error 43. before the mark the card was working perfectly and i had no problems with it. I hope someone can help me out. tried reddit and saw lotta toxic comments on my post :')
    i hope someone can help me with my problem. should i reset my bios? if i do what are the cons of it
