Question Motherboard or PSU Issue ?

[Pigus]

Hello,
Not sure if this is Motherboard or PSU problem. My PC wont boot right away after hours of being shutdown or in sleep mode. Pressing the power button only causes LEDs to flash or sometimes no power at all. Lately, I've found some workaround by unplugging and replugging my keyboard (corsair strafe mk1) until the keyboard's default LED colors light up (red and white). I also tried to recreate this by using a generic keyboard with no LEDs on it and got the same result as my main keyboard.

Ryzen 7 5800x
MSI B550m Mortar Wifi
Gskill 16x2gb Trident Neo 3600 Cl16
Seasonic Focus+ 850FX

If unplugging and re-plugging a USB device is what fixes this, then it sounds like it's a motherboard issue. I'd first recommend to update your BIOS if you haven't done so recently.

Thanks for the reply. The motherboard is already running the latest bios and still has the same problem.
