Monitor does not wake up after sleep

[magedkilada]

Hello, I have an El Capital Build Pro 3,1. my graphics card is nvidia GTX 960. Motherboard is Gigabyte-GA-Z170MX-Gaming-5. When i wake up the computer from sleep the monitor does not connect and all i get is snow. The mouse works fine during that time. I have to completely restart before I get the monitor to turn on.
Help Please.

Use iMac 14,2. Broken Sleep can be caused by USB or Powermanagement.

You have NullCPUPowermanagement installed which isn't needed. Remove it.

Thanks a lot, removing NullCPUPowermanagement and setting darkwake0 fixed it!

I have this motherboard and cannot wake from sleep as monitor will not come on, how do we remove nullcpupowermanagement to make it sleep and wake? I already have darkwake set.
