after replacing my initial motherboard (MSI b350 tomahawk), with the AX370 gaming k5, im still suffering the 'CPU fail' led lighting up when i try to post. The CPU has been tested working by a 3rd party, all of the other components in the system are either recycled from my old system (apart from the ram) or are new.
When initially tested in the new board, i tested with only the CPU, no RAM, or GPU or HDDs connected, i had a CPU fail when this occurred, a repetition of the issue i had with the b350 board, i did not test with any other components installed after this due to the fact that i had already done that on the b350 board, and had the same issue.
i have a few ideas that could be the cause of the issue:
- MOBO shorting on my case (though my current MOBO does not)
- PSU not supplying power correctly on the 2x4pin connector for the CPU (though, my current system works fine, but does only use one 4pin for the CPU)
- Does POSTing on a UEFI board require there to be at least one stick of RAM to allow the UEFI lo load itself before it can check any components? (i know ram is necessary for a full boot, though, to test hardware such as the CPU i am not sure if RAM is needed, the RAM led did not light without it)
other than the above ideas, i am completely lost, everything should work, the board looks fine, and powers on, it does not turn off after an amount of time, it will just stay on effectively idling with no RGB LEDs on, just the CPU LED on. The PSU should be fine (it happily powers an FX 8350 with no issues), and no MOBOs have ever shorted out in my case before.
Build System:
CPU: AMD Ryzen 7 1700
MOBO: Gigabyte Aorus x370 Gaming K5
GPU: Powercolor PCS+ AMD R9 380 4GB
RAM: 2xcorsair vengeance 8GB LPX DDR4 @2400MHz (on the QVL)
PSU: XFX TS 750W
CASE: NZXT Pahntom
Current (Working) System:
CPU: AMD FX 8350
MOBO: Asus m5a78l-m/usb3
GPU: Powercolor PCS+ R9 380 4GB
RAM: 2xHyperX Fury 8GB @1866MHz + 1xCrucial 8GB (dont know the model) @1600MHz DDR3
PSU: XFX TS 750W
CASE: NZXT Pahantom
any help would be appreciated.... as all of the components seem to be working fine, unless i try to assemble them
