Dead Nvidia GTX 770 (No-Signal)

Jun 4, 2018

I recently picked up a GTX 770 that use to work fine, but now displays no signal whenever i boot the pc (Card lights up and fans spin). However, my GTX 660 AMP Edition card works just fine.

CPU: I7- 3770K (Noctua NH-D14 Cooler)
MOBO: Asus Z77 Sabre Tooth
RAM: G-Skill Ripjaw X-Series (4 x 4GB)
PSU: ThermalTake Smart Series 750W
Graphics: GTX 660 AMP Edition (Current Card) | Nvidia GTX 770

Things I've Tried:

  • Update Bios

    Tested card in several PCs (No-Signal on all)

    Ensured all cables are properly connected

    Ensured card is properly seated

    Newest driver and uninstalling old one. (However there is a system compatibility error)

    Booting in safe-mode (integrated graphics)

    Clean install of Drivers

    Pc does boot with integrated graphics, but in device manger nothing is there (Hidden Devices is ON.)

    Dissembled card (All Surface Mount Components and PCB Traces seem to be OK.) (Thermal Paste should be redone)

    Probably more, just can't remember.
So i'm thinking the card is dead since the pc wont even post, just starts up and displays no signal. However, the card was free so i don't really care to much about it.

Just want to know if i've done everything i could.
