Windows 10 Desktop: Locks up within an hour after login, sometimes before. Blue screen -> "Select proper boot device".

For the past week or so my PC has randomly been locking up, causing all programs to become unresponsive, forcing me to shut it down. It would sometimes go for 5 hours or longer, but now it never lasts past 1 hour.

I have gone to sleep after it freezing without turning it off, and when I wake up to check on it it is at a black screen with white text saying "Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key" and I have no idea what to do and just press the power button (no need to hold it in this case) and it shuts down then comes back on immediately (but sometimes it doesn't come back on afterwards, weird). It occasionally hits the blue screen after 5-10+ minutes (the one saying something went wrong we are collecting data), then it goes to the select proper boot device screen. But, sometimes it takes longer to reach the blue screen.

I've read countless posts about PC crashes and lock ups but nothing seems to be like mine. I can't keep it on long enough to run a malware scan (I'm pretty confident I don't have a virus) or CCleaner (it just got 29% through CCleaner then crashed again). For what it's worth, my hard drive seems slow and I believe it could be the problem but I have no way of knowing.

My specs are:
Intel i5 4670k
Radeon R9 270x
Gigabyte Motherboard (that's all I know)
8GB RAM
WDC WD something something 1tb hard drive
Power supply I'm not sure but I can probably check if it's really important.

I've hard powered my PC down more times than I'm comfortable admitting and assume this will eventually lead to a bigger issue. Please let me know what I can try. Thank you.

P.S. I don't feel comfortable messing with the parts of my computer, but if I have to I have no other options I suppose. I bought it on ibuypower over 3 years ago and all I've done is replace the GPU once (over 2 years ago).

I have a pastebin from crystal disk info: http://pastebin.com/tXm4DWWi

I believe my disk may be "dead" as someone else told me. Any recommendations on what to do in terms of backing up my data and getting a new hard drive?
