Desktop stuck on startup

[Thijzo]

When i power up my desktop it starts the startup procedure but 99% of the time it seems to get stuck. That remaining 1% it boots just fine and everything seems to work. When it fails to boot, the system powers on, the fans start running and the motherboard debug-led gets stuck on 24. But the keyboard, mouse and screen do not power on and do not seem to accept any inputs. And it's absolutely driving me nuts. I have done everything i can think of that could solve this problem:

•  Removed individual components to check for damage
•  Checked the PSU 
• Reset CMOS
• Fresh windows install
• Updated drivers

My specs are:

• Windows 10 home 64-bit

• MSI Z97-GAMING 5 (latest bios)

• Intel i7-4790
• Integrated Graphics (GTX970 died a while ago)

• Kingston HyperX Fury Red 2x8GB DDR3-1866 CL10 Memory

• CX650M — 650 Watt PSU

• Crucial MX100 - 128GB SSD (Boot)

• WD10EZEX-08M2NA0 - 1TB HDD (Storage)

Any help would be greatly appreciated. My (admittedly limited) know-how has been exhausted.

seems like a possible dying motherboard. happened to me long ago. it booted into desktop fine but applications often failed to load on startup. eventually it got worst. and then it just wouldnt boot up anymore.
