Overclocked GPU voltage black screen GTX 1070 (water cooled). Need assistance.
Overclocked GPU voltage black screen GTX 1070 (water cooled). Need assistance.
The system features a GTX 1070 Founders Edition (watercooled) GPU paired with an AMD FX8350 CPU (also watercooled). It runs on the ASUS m5a97 R2.0 motherboard. The configuration includes 8 GB of DDR3 RAM (32 GB total, split across four sticks). Power supply is a Thermaltake Smart 750W 80 Plus Bronze unit. Storage consists of a 240 GB SSD and a 2TB hard drive. Occasionally in July, I watercooled my Nvidia Founders Edition GTX 1070 using the Kraken G12 mounting kit from NZXT. After some overclocking with MSI Afterburner, I reached the maximum voltage limits supported by the software. Other components underwent stress tests for 15 minutes each without issues, but when I pushed them further in Unigen Heaven, artifacts appeared and the screen went black. By September, the screen remained dark.
Recently, I purchased a used GTX 480 from eBay three weeks ago to check my system since I lacked a spare GPU and had no integrated graphics. Access to my original PC was limited until last week. I attempted various fixes: flashed BIOS, removed CMOS battery, cleaned RAM, swapped RAM slots, reconfigured PCIe slots, changed monitor cables, switched HDMI and DisplayPort connections, and even connected an Xbox via HDMI. After plugging in the GTX 480 alongside the spare GPU, I regained access to my PC. Device Manager detected the GPU but reported driver problems.
Updating drivers for the GTX 1070 consistently failed, even after installing newer versions and older ones from Nvidia’s official site. Restarting after each installation would reset drivers, resulting in poor resolution on the GTX 480 and persistent issues with the original GPU. The Nvidia control panel also failed to recognize my GTX 1070, and other applications like MSI Afterburner only acknowledged the GPU when using GPU-Z.
VBIOS flashing resolved the 0 MHz clock issue but did not fix driver problems or improve screen visibility. I still struggle to install the latest drivers or view a clear display from the GTX 1070. Despite these challenges, I’m able to use my PC for everyday tasks and light gaming with the used GTX 480. My intention is to eventually upgrade to Ryzen 4000 series CPUs and an RTX 3000 GPU, but fixing this GPU remains a priority.
Thank you for your assistance. I appreciate any guidance you can provide. If possible, I’m grateful for your support, but at least my PC will serve me well for daily use and casual gaming now.
I reached the maximum limit that MSI afterburner provides with voltage overclocks. For all the others, what do you mean by "the other ones"? A GTX480 would need different (older) drivers compared to a GTX1070. I suspect your GTX1070 might be affected. Just use the GTX480 and let nVidia identify the GPU so it can provide the appropriate drivers.

Just use the GTX480 and let nVidia identify the GPU so it can provide the appropriate drivers directly.
