Faulty CPU
Hi, your i5 4460 seems to be functioning properly with the motherboard and peripherals. The issue you're experiencing when switching to the i7 4790 appears to be related to the CPU itself. Despite the motherboard supporting the H97M-D3H model, the system only powers on and then displays a blank screen with fans spinning. Have you tried resetting the BIOS or checking for any firmware updates? Also, ensure the RAM is correctly installed and the power supply is stable. If the problem persists, consider testing the CPU directly with another motherboard to confirm if the issue is hardware-related.
These models belong to a series known as Devils Canyon, which came out after the original Haswell CPUs. Newer BIOS updates are usually needed for them. For your H97 motherboard, I wasn't surprised by this requirement, but you should check both your board's version and the latest available on their website.
Without another motherboard available for testing, it seems worth trying. Perhaps the CPU isn't compatible with the memory, so experimenting with different setups and slots might help. If those changes don't resolve the issue, a BIOS update could be the solution. I verified compatibility on their website, indicating the CPU should work without needing to change the version.
Since the i5 functions, it seems it might fit well with other systems. You're concerned about upgrading the BIOS to a beta version, which could introduce problems.
I’d check whether it supports changing to another BIOS, such as pressing F5.
Reducing the BIOS might assist. If F7 fails, the likelihood of F5 succeeding is uncertain.
F2 and later support the 4790, so issues might stem from the flash rather than the BIOS.
