I took out the CMOS battery, pressed the power button probably 10 times while the battery was out and PSU was unplugged. Also tried resetting the CMOS with jumpers as the manual directed.
I must have power cycled this 40 times with varying amounts and types of components. I've unhooked everything besides the components listed below, this processor doesn't do onboard video and I don't have a spare GPU that I trust to boot (the 390X is a big draw on power.)
It boots as it says in the title every time unless my keyboard isn't plugged in or there's no RAM.
With keyboard and ram, it's the ASUS splash, and all that says is the standard one line at the bottom about pressing F2 or DEL to enter UEFI BIOS. Holding DEL or F2 does nothing at any point, even holding it from the beginning of the boot.
If I boot without a keyboard it goes to the Motherboard splash screen > does the POST beep > does another beep completely distinct from the POST beep [to alert there's no keyboard] but still short > takes me to the BIOS screen (American Megatrends). There it says:
Starting without RAM is a looping beep series: long, short, short, short.. Obviously nothing else happens.
Z97-A mobo i7
4790k + old H40(? I think.)
R9 390X
CX750M PSU
So what are we thinking here? Probably something wrong with the motherboard if BIOS is posting but nothing loads after the splash? Or is there still a chance it's the PSU?
I've been fixing and building my own and a handful of other peoples' computers for years now, but this has me completely confused. Today I'm borrowing another PSU so I can finally rule that out. I feel fairly certain that it must be the motherboard at this point.
I'm at work until this evening so I won't be able to answer/test right away. Thanks for any help in advance.
