Possibly dead 4090
Possibly dead 4090
Hello!
Match finished in CS2 and noticed HDR was off. Checked settings but option wasn't available. Examined Device Manager, showing my 4090 when opening it, yet error appears (code 43). Windows can't recognize my Zotac 4090. PC is using Intel integrated graphics at the moment.
From what I understand, this points to a driver problem. I reinstalled drivers three times—once via Windows, once with DDU, manually—but nothing helped.
The GPU is three years old. Fans are spinning and lights are on. Could it be dead? I've never seen a dead GPU before, so I'm not sure what signs to look for.
PC specifications:
Motherboard: Gigabyte Aorus z790
CPU: i9 13900k
GPU: Zotac RX 4090
RAM: Corsair Vengeance DDR5
Power Supply: Asus 1200W
When opening device manager under display adapters it displays my 4090 but clicking on it triggers an error (Windows has stopped this device due to reported issues. Code 43). Using GPU-Z, check if any fields display zero or N/A or unknown values. If found, your GPU may have stopped working. You might consider reflashing the VBIOS on the card, but be careful—if it has a warranty, send it in for an RMA as changing the VBIOS could void the warranty (since you’ve altered the card).
Check Reliability History/Monitor or Event Viewer for any error codes, warnings, or informational events. Search for entries near the start of the GPU issues. Power down, unplug, and open the case. Remove dust and debris, then confirm all components—cards, connectors, RAM, jumpers, and case connections—are securely positioned. Use a bright flashlight to look for any signs of damage.
Card not covered by warranty. Reached out to Zotac already. Now we'll attempt all options. Mobo bios is current, updated during the GPU issue fix.
Mobo bios is current. The update was made during a fix for the GPU error. For clarity, please reference the BIOS version instead of the latest. There are numerous discussions on forums about the latest release, but it seems a BIOS update is still needed. You haven't received your GPU-Z results yet.
I'm not very familiar with Event Viewer.
I drained the power from the system and unplugged the GPU to check for connections, cables, and other issues. I didn't see any signs of damage or problems.
Sorry, I overlooked that. When I view the cpuz graphic section, it indicates the PC is utilizing Intel integrated graphics, with no mention of a GPU. BIOS version is F17, dated 09/18/2025.
Event Viewer takes longer and requires more work to explore and grasp. To assist, please refer to the following links: https://forums. https://learn.microsoft.com/en-us/shows/...ent-viewer Reliability History/Monitor is significantly more user-friendly, and the timeline format can highlight trends. Check if understanding what CPU-Z suggests, as per @Lutfij's advice, helps. Then investigate any errors that match when issues started or happen.
Sorry, I overlooked that detail. When I view the cpuz graphic section, it indicates the PC uses Intel integrated graphics, not a GPU. GPU-Z and CPU-Z don't show anything about the GPU. Mobo: Gigabyte Aorus Z790. It's important to note that Gigabyte is the board brand, while Z790 refers to the chipset it uses. Aorus represents a series similar to Asus's ROG lineup—what is the precise model of your board?
It has been some time since my graphics card stopped working properly...or at least Microsoft installed a driver that made it appear dead.
I looked for guides on fixing video cards using the IGPU, finding tools that work under Linux which can test GPU memory.
I didn’t progress much because the GPU still functioned well in Linux, so I realized the problem was likely with the Windows driver.
Then I spent half a day trying to resolve it instead of reinstalling Windows.
