strange shut down/hibernation

So I just got home about an hour ago and I turned on the laptop like i usually do. It started right up (I usually just hibernate it) but after about 3 minutes, the screen went black an then it made it hibernation/shut down noise. I waited a few seconds and I booted it back up but it threw a bsod at me; 0xc0000411 hyberfil.sys, dumped and shut down.

I waited about 2 minutes this time and booted it back up and this time it booted fine but again I only got a few minutes before it did it hibernated again. I repeated this cycle about 4 more times and 3 times out if the 4 it booted fine but would only last a few minutes. Although one time I booted I got a cmos error (sorry I don't know the exact error and I can't get it to replicate, I tried) and it changed my system time to 2008 (I'm guessing the year it was made?)

I tried booting into safe mode to see if I would get the same results but so far it's a bust. Pressing the button, F8, will make it look going to but it doesn't.

It just started doing this and I'm at a loss with how to troubleshoot. Any help will be greatly appreciated!

I posted in hardware because I thunk it might be the hard drive going but if I'm wrong (I usually am lol) please send me to the right one!
