It could be a PC crashing the GPU.
I owned a 3090 that failed roughly eight months ago. Research showed this model had a batch that would short after use but no recall was issued. I purchased a used 3080Ti, which also stopped working last night. Playing a game (New Sniper Elite) the screen would go black yet continue running without any display signal. Restarting the PC didn’t help; it kept refusing to power on unless the GPU was removed. This mirrors what happened with my 3090. I swapped out the PSU for another identical unit, suspecting a similar issue might be on the motherboard. I’m worried about adding another GPU just to risk failure again. Maybe something is wrong with the hardware or timing. If not, I might need to buy a new PC and sell the old parts, clearly noting the problems. It could be a short circuit or just bad luck. Temperatures were normal during idle and load. CPU specs: AMD Ryzen 9 5900X (38°C) / 80°C; cooler: 360mm AIO Corsair (38°C) / 75°C; motherboard: ASUS ROG Crosshair VII (35°C) / 45°C; RAM: Gskill 32GB 3200MHz (33°C) / unknown; GPU: RTX 3080Ti Gigabyte (35°C) / 78°C; PSU: SeaSonic 1000W.
Unless you purchased the card from someone else, I’d think most used 30 series cards were likely mined for crypto, possibly during the GUPs era. I’d personally look for a budget Radeon 6600 to test if it would fail in your system. If it doesn’t, bring it back and upgrade to another model. If it does fail, hopefully there’s a return window and you can switch to a different setup.
