RX 6400 on Dell PTIPLEX 3050 fails to appear on screen.
Your OptiPlex 3050 SFF setup seems to have several potential issues. The RAM is installed but doesn't appear in the system, which could mean a driver problem or incorrect installation. The GPU isn't showing up at all, even though you think it's connected properly—this might be due to BIOS settings, power delivery, or driver configuration. The fan spinning when powered on suggests overheating, possibly from inadequate cooling or a faulty PSU. Check the motherboard manual for PCIe 3.0 x16 compatibility and ensure your GPU supports that interface. Update all drivers, verify BIOS version matches your hardware, and test with a different GPU if possible. If the issue persists, consider cleaning dust from vents and fans.
