Windows 10 shuts down, but PC won't
- OS: Windows 10 Home (w/creator's update)
- Asrock Z270 Fatality Gaming K6 (UEFI bios ver: 2.00)
- i5-7600K (not OC'd)
- Corsair Vengeance 16 GB DDR4 3000 (2x8)
- EVGA GTX 970 SC
Built this rig a few weeks ago. Everything is working fine, except for this odd power issue. When I shutdown the PC, Windows will shutdown, the monitor goes black and loses signal as it should ... but the PC itself stays fully powered, fans running, power light on solid, and all mobo LED's lit. It does not appear to be in any kind of sleep or hibernation mode, keystrokes nor mouse will wake it.At this point I can press & hold the power button to fully shut it off. It will start up perfectly fine every time. This also happens when I put the PC into Sleep mode. I've gone over power settings both in the BIOS and in Windows. Everything seems to be normal. I've tried unplugging all USB devices (except keyboard), no luck.
When it does this, all I can do is press & hold the power button to shut it off fully. Nothing will wake it. It's as if the PC is off in every way except power. Even the reset button is ignored.
I should mention this problem is somewhat intermittent. Occasionally shutdown and sleep will work, but fails 80 to 90% of the time.
Thanks for any assistance!
