PC - Crashing randomly. Need help fast!

Hello!

I need some big help. Recently my pc started crashing and crashing and after the crash it takes around 3 min to start again... I have no idea what's going on and I have no idea how to actually find out what's going on or what I should do.

The things in my pc.
AMD FX -8350 8 Core processor 4.00GHz (No I don't overclock.)
8GB ram
x64 Windows 8.1
MSI Twin Force Gaming GEFORCE GTX 770
Corsair RM 850 watt
970 Extreme 3 R2 or something like that...

I hope you guys can help me out. My pc isn't even 1 year old and it's starting to crash at random moments, while I'm just browsing my on Google Chrome. I wasn't even gaming but sometimes it does indeed happen when I'm gaming.

Please help me out or tell me what to do because I'm in my exam period and I need my pc! Thanks already.

Greets.

Forgot to add this, the temperature of all my cores are around the 20. Didn't check this when I was gaming I was just writing this! I also you 2 screens.

What are your storage devices?

My hard drive is an old one, took it from a Medion pc.. has around 1TB... Don't think there's anything wrong with it.

Under computer management, look in Event Viewer -> Windows Logs -> System and look for Error marked as Kernel Power. Look for warning around those and see what they say.

Name resolution for the name wpad timed out after none of the configured DNS servers responded.

Display driver nvlddmkm stopped responding and has successfully recovered.

Those are the warnings I see... A few of them after and before the Kernal Power errors.
