Hi. I'm putting together a sort of new build for my parents, and I can't for the life of me figure out why it won't power on. The power supply is brand new, tested, works fine. Motherboard and CPU are also new. The RAM is from my personal current desktop and was working when swapped it out for faster RAM. The case is an old Cooler Master HAF, but the panel switches will work if I plug them into the MB of a very old spare desktop. All the cables are firmly seated in their respective sockets. It SHOULD work. Now, as it happens, I accidentally ordered two identical MBs, so just for the heck of it I unpacked the second one and hooked up the power cables and panel leads, then tried turning it on sans CPU and RAM, with a spare case fan plugged into just to see if it would turn on, but it didn't work either.
I'm thinking the panel leads must be the culprit here, somehow. Even though they work with a different MB, maybe they're still failing to connect with the panel on this one, although a jumper should be a jumper, right? Or maybe the panel is laid out differently from what's shown in the manual (and printed on the MB) and I'm not connecting them correctly, although I've tried a couple of different ways to no effect.
FWIW:
CPU: AMD Ryzen 5 3500X
MB: ASRock B550M Pro SE
RAM: G.Skill Ripjaws DDR4-2666 32x2
GPU: MSI GeForce GTX 970
PW: BeQuiet Straight Power 11 550W
Case: Cooler Master HAF full tower
A Samsung SATA SSD
Please Help?
