Hey there, welcome! I see you're setting up your system with a new motherboard and CPU. It sounds like you're trying to get everything working smoothly. From what you've shared, the BIOS is up to date (2305) and the CPU list confirms compatibility with i7 models. You've already tested other CPUs and found issues only with older ones, which makes sense.
The fact that removing the GPU and using the onboard CPU helped suggests the GPU might be causing the problem. Also, your PSU is rated for 430W, which should handle an i7-4790 if it's properly cooled. Make sure the power supply is stable and consider checking the fan speeds—if they're not spinning properly, that could affect performance.
If you're still having trouble, double-check the BIOS settings for any conflicts or updates. Let me know what you try next!
