I'm building my first computer in over a decade and after hours of putting all the components together, I plug it in for that agonizing first power-on. The motherboard's DRAM_LED glares continuously regardless of what configuration I put them in. I do the MemOK test each time and it fails the battery each time. They're DDR4 PC3200 modules that should work just fine but the mobo won't get past POST. I've even made sure everything is getting power, too.
