Computer turns itself back on/Doesn't Sleep

[LVanBuren]

Title says it all but here's some details.

It will turn itself back on after either a few seconds or a few minutes. It tends to vary.
Whenever I put it to sleep it sometimes does, other times it will just cut the display and not respond. This also happens whenever it sleeps from activity.

I've also gotten a bluescreen (of death) about twice. Whenever it turns back on I guess something goes wrong and it crashes.
This just happened when I came back from work. I turned it off and returned to a bluescreen after about 5 hours.

This is really annoying and I'd appreciate any helpful info.

Specs:
EVGA GeFroce GTX 970
Intel I5-4690K CPU 3.50GHz
16GB Memory
Windows 7
AsRock z97 pro Mobo
