My PC turned on at night 2 times in a row... it seems to be random at first it turned on somewhere at 2:00 at night the second time it was at 6:48 in the morning. What could be causing this?

Also could it be something to do with MSI Afterburner? because it started to do that the first night after my PC had Afterburner installed... or is it just coincidence?

Should I just turn off my PC using the Button on my Power Stripe?

Which leads me to another question
My PC is connected to a power stripe but I don't have a surge protector or a UPS, and I live in a private home that may not have very stable power. Should I get an UPS?

I have a good Corsair AX860 Power Supply does that matter? My PC runs fine it seems. Or should I still get a UPS?

I'm using Windows 8.1 Pro
MotherBoard: Gigabyte H87M-D3H

Sorry for all these questions, but I hope I'll get some answers before night comes so I will know what to do.
 
Solution
The PSu should be fine. I've had issues with Windows actually being the culprit, installing "critical updates". You can usually control what's allowed to boot the PC via the BIOS, though. Disabled everything except BIOS and it's been fine since.
