Computer won't sleep at night.

My understanding is the cpu fan does not care about all those settings. It only comes on with temperatures that indicate the fan is needed. Other than the fan coming on what other indications do you have that the system has woke up.

That is actually a very good question! I'm pretty sure the power light is still on.

Is there other signs to look for? Moving the mouse seems to just light up the screen, it doesn't seem to boot or anything like that [but it is an SSD]

Update your display driver: Enable Automatically deliver drivers via Windows Update (Step 3) then run all rounds of Important and Optional Windows Updates. There may also be a performance update that affects this.

If no newer Display driver is delivered, check the Support Downloads webpage for your model PC or device. Try all available drivers including older to see which will support Sleep.

The optimal settings are the one AddRAM showed you. Screensaver is not needed unless you have a CRT monitor.

If all else fails there are other steps here for Sleep Mode Problems

Drivers are fully updated.

Going to check the AMD & Asus for drivers.

Screensavers had two purposes. They were to save the screen, as the name implies. They also entertained. Quite often I have Johnny Castaway [stolen so much it was actually made public domain] on my computers, but I have not tried it with Win7 to see if it even works. I also use my screensaver as a way to measure how long it's been since it's been used...

Taking a look at the Sleep mode problems. Edit: Already been through that one too

If you're using third party screensavers then you may not need to look much further for the problem blocking sleep. That's even worse than I thought.

I'd also scan your PC with Malwarebytes because their downloads are a notorious path for infection.

I have yet to try 3rd party screensavers...
