" rel="nofollow - My PC stopped waking from Sleep

Without exception, I put it to sleep. Power light blinks, will not wake on mouse or keyboard input (lights on wireless controller off). Only way to get out of this mode is hold down the power key for 5 seconds, wait 30 seconds, then re-power up. Tried changing C3 states to no avail, tried plugging into other USB ports.

This used to work, only thing I can explain is recent update to Windows 10 build 1703, no BIOS changes.

Any ideas?

thanks!

i7-5820K
64GB DDR4
BIOS P1.7
Windows 10 1703
wireless keyboard/mouse controller plugged into USB 2.0
BIOS C3 enabled, C6 disabled, Deep Sleep Disabled

Dear Atoro,

Thank you for choosing ASRock.

Regarding your case, we have built a system to verify, system can wake from sleep properly.

This is our system configuration:

CPU: i7-5820K

We provide some suggestion to verify.

1. Reinstall your VGA driver.

2. Update BIOS to P1.90 with BIOS default setting.??o:p>
