Windows crashes even after a new windows install every other boot

I've have windows 10 on my PC crash every other time I would boot it. For example I would start up the pc login to windows and maybe watch youtube or play some games for around 15 min and then BOOM! blue screen, sometimes it would even crash 5 seconds after I login. I would boot it up again and this time it doesn't crash, even If I leave it running overnight. It always seems to happen every other boot. Know that I had this problem even after I got a new ssd and a new installation of windows on said new ssd and just put all my old files back in. What's even more confusing is that each crash brings up a different error code ranging from System service exception, to Kernal security check failure and a couple others that I can't name off the top of my head. I've been banging my head over these crashes and would really like a solution that doesn't require just wiping all my drives clean and reinstall.

My computer specs are as follows if it helps:
Cpu: Ryzen 1700
Cooler: Enermax Liqfusion
Mobo: ASRock X370 Killer SLI/AC
Ram: 64gb trident Z ram 2400 mhz
Gpu: Two gtx 970s in SLI
Storage: One 250 GB samsung Evo 970 m.2 ssd and two 1TB Western Digital Blue Hard drives
PSU: Supernova NEX 650W 80+ gold

Try using one video card, as it appears you don't have an adequate power supply for a 970 GTX SLI.

Alright I'll try running with a single card for a day and see If I still crash.
