Not sure if this is a problem with my board, or PSU or whatever.

But I've been putting off for some time now.

Whenever I stick my PC into sleep mode, waking up never happens properly.

I can move the mouse, click the keyboard, press the power button. The PSU will start up, but then stop, and keep doing this, continuously.

Does this happen to anyone else? Do I need a BIOS Update? / a setting changed?

Thanks!
