I have a bad feeling about this. Press power button and get only flashing leds on GFX_PUMP FLEXBAY board. Press power supply test button and I can hear its internal protection circuit click. After PSU dead until unplugged. So I remove all RAM, peripherals, power, and usb connections from MB. PSU test button will power up fans, vents, and internal lights. Same result for PS1 connected to MB. Connect PS2 to MB and only get PSU protection circuit switched. Never any beeps. Is my MB cooked? Is it worth replacing or should I just upgrade MB, CPU, and GPU. I like the case too much to just junk it. Thanks
Aurora R4 ALX, motherboard cooked?
