You're facing a persistent challenge with your RTX 5080 setup. The workaround you tried—disabling the iGPU and enabling CSM in BIOS—did help, but it’s worth exploring further. This approach seems to address some driver conflicts, yet the issue may still stem from other factors like motherboard compatibility or power delivery. It’s not uncommon for RTX 5080 models to have quirks with certain configurations. To get a clearer picture, consider checking official documentation for your motherboard model and verifying if the RTX 5080 is listed as supported. Additionally, running a system diagnostics tool or consulting community forums could reveal if others have encountered similar problems.
Activating CSM usually disables Secure Boot and stops Windows 11 from starting. Are you running Windows 10? If your machine is functioning now, I don’t see a problem. Secure Boot stops unauthorized access to the boot process, which protects against malware on stolen drives. Most everyday users don’t require this extra layer of security. Have a great day!
Do you have the most recent UEFI (BIOS) upgrade for your motherboard? That should be the first step I take to fix this problem. Also, your NVidia driver version 576.52 is outdated as of today—please install it now. CSM must remain disabled for Re-Sizeable BAR to work properly, especially if you play games. Even though there are some recent issues, Secure Boot should stay enabled for security reasons; it blocks many types of malware like bootkits and rootkits, which is important for both home users and anyone else.
