I recently transferred my PC into a new case and upgraded the CPU from 3600X to 5800X, and changed the graphics card from 3060Ti to 4070Ti. After a week of normal operation, the BIOS displayed strange visuals—lines cutting across, distorted colors, and the green indicator shifting to blue. When I booted into Windows everything worked properly except for the startup screen and BIOS, which were affected. Have anyone experienced this issue before? What steps should I take to resolve it?

Hello! Your bios are now up to date, but you're still facing issues. It looks like disabling CSM might help resolve the problem. There doesn't seem to be a specific reason against it unless you're unsure about its function. Consider testing that setting next.

The Compatibility Support Module (CSM) is part of the UEFI firmware designed to maintain compatibility with older BIOS systems by mimicking a BIOS setup. This enables legacy operating systems and certain ROMs that aren’t UEFI-compatible to function. CSM also adds required System Management Mode (SMM) features, known as CompatibilitySmm, which extend the capabilities of the UEFI SMM. These features are optional and depend heavily on the specific chipset and platform. For instance, it can offer legacy USB support for keyboards and mice by replicating their classic PS/2 behavior. In essence, you typically don’t need CSM unless your hardware requires it.
