According to widespread user reports from Chinese tech forums and Reddit communities, multiple RTX 5090 and 5090D graphics cards are failing permanently after standard driver installation. The issue affects both the standard RTX 5090 and the export-modified 5090D variant released for the Chinese market on January 30th. Users report consistent failure patterns: upon initial driver installation, displays go dark, and systems permanently lose the ability to detect the GPU through both DisplayPort and HDMI interfaces. Hardware failures have been documented across multiple board partners, with Colorful, Manli, and Gigabyte cards showing identical symptoms. Third-party vendor reports sometimes indicate potential IC burn damage, suggesting hardware-level failure rather than recoverable software issues.

You can now play with NVIDIA GeForce graphics card BIOS like it's 2013! Over the last decade, NVIDIA had effectively killed video BIOS modding by introducing BIOS signature checks. With GeForce 900-series "Maxwell," the company added an on-die security processor on all its GPUs, codenamed "Falcon," which among other things, prevents the GPU from booting with unauthorized firmware. OMGVflash by Veii; and NVflashk by Kefinator (forum names), are two independently developed new tools that let you flash almost any video BIOS onto almost any NVIDIA GeForce graphics card, bypassing "unbreakable" barriers NVIDIA put in place, such as BIOS signature checks; and vendor/device checks (cross-flashing). vBIOS signature check bypass works up to RTX 20-series "Turing" based GPUs, letting you modify the BIOS the way you want, while cross-flashing (sub-vendor ID check bypass) works even on the latest RTX 4090 "Ada."
