My pc has been running great for about a month now. Before bed I press the sleep button on my wireless keyboard and everything shuts down fine.
After work, when it's time for movies or music or games, I press the same sleep button on the wireless keyboard and everything starts up where I left off the night before without a hitch. Tonight was different.
After pressing the sleep button to wake from yesterday, all lights and fans light up and spin as normal but after a few seconds returns to sleep. The only way I have found to wake it is to press the power button on the case itself. I haven't updated or changed anything for at least a week, this just started out of nowhere. Any thoughts?
I've checked Google but only read that I need to go into either BIOS or Control Panel to enable the features I have been using for a month.
I'm running
Windows Ultimate X64
i5 4690k
z97x-sli
Crucial 250gb SSD
550w Rosewill.
My temps are great so not overheating.
Edit: After trying to wake several times in a row it stayed awake but only after 16 tries and only once.

I know windows 8(and 8.1) have a lot of issues returning from sleep if your have fast shutdown/startup enabled. Mine had a very similar issue, but it would only do it sometimes so it really had me scared, since I had just built the PC at that point in time.

That link is the one I've saved and I refer to every time I've setup a new Windows 8 system. The pictures make it a lot easier for me. =D
