The Intel DX79SI motherboard displays a black screen with a "0_" in the bottom right corner likely due to an unrecoverable error, such as POST code 0x5F, which indicates a critical failure. The document suggests starting with PCI troubleshooting, meaning the issue could be related to PCI devices or components. Checking PCI connections, reseating components, or diagnosing hardware failures may help resolve the issue.
