My computer restarts randomly

[DigitalNinja]

OK so the backstory,

My computer had a 1Tb HDD, that was nearly full, I recently updated my mobo and CPU, the mobo caused some problems that resulted in a few 100% disk usage issues, ultimately resulted in a fresh install of Win10 because I couldn't find a solution

Fast forward a few months, about two days ago, I got a bluescreen that I somehow haven't fully recovered from, It tanks my HDD speed, so much that a 30 second boot up to login became 30 minutes, and was constantly and consistently at 100% disk usage the entire time. Playing games were a nightmare, but would often lead to a BSOD shortly after log in.

So I managed to get two 120Gb Kingston SSDs, I've managed to install one that has the OS on it, once that was all up and running I decided to redownload some programs I used, Steam, Discord, Chrome etc etc, but now the problem I'm facing is that my computer will randomly restart, thankfully the SSD makes it boot back up in less than 30 seconds, but it usually does it when it's downloading something, or when it's actually being "used".

It took me three attempts to download, and another 2 attempts to install Chrome, I'm currently downloading Rainbow Six: Siege on the second SSD and It's only restarted once, I have yet to plug in my old HDD to wipe it and use it as basic storage.

i7 8700k processor
GTX1070 Gigabayte
Maximus X mobo
2x 120GB Kingston SSDs
1Tb nearly 8 year old HDD.
600watt PSU


Now I obviously don't want it to be randomly restarting on me, especially when I'm playing games and or streaming. Is there a fix for this or am I royally shafted?

My canned random reboot Rant
Random reboots are usually caused by the PSU, the RAM or software AND in that order of likely-hood.
PSU - If you can borrow/swap a PSU for testing. sibling/friend you can swap out the PSU and each system will be testing the other.
RAM - run the system with one stick of RAM see if stability returns if not Test all the RAM with memtest 86 for three passes or overnight. if you get no 0 errors after more than three passes the ram is good. with the random reboots I would suggest running this test after the PSU swap or after the PSU has been cleared.
Software - Drivers or other issues can cause reboots. Boot to a linux distro on a USB drive. mint linux will boot to memtest86. you can run the OS from the USB and await reboot.
end canned rant

I'll certainly be looking into possibly getting a new PSU, as it's the only thing in my rig that hasn't been updated since getting it nearly 10 years ago, embarrassing really.
