Windows 10 boot issue

Hello! So let me get started, one day I come home from school and my computer is taking a pretty long time to boot. I surf the web per usual when it's time to go to sleep I turn it off like normal. Next day when I come home from school, I turn on my computer but it was booting really really slow. I decided to run CCleaner and Malwarebytes to see if I have anything unusual in my computer. After that everything was fine, restarted my comp 2 times booted up really quick. Next day the problem came back where I would turn on my computer, it would try to boot I see the little Microsoft logo with the ring of dots then boom monitor shuts off but computer is still running. After restarting it a couple times it kept happening again and again. Ended up deciding that it was my harddrive so I bought a new one with an SSD. Fast forward until today, I get the SSD and HDD in the mail, open up my computer, take out the wires for the SSD and plug it in. Started to install Windows, ended up working again. Downloaded AMD drivers and google chrome, watched a LinusTechTips video and how to install the hard drive w the ssd. Did all that restarted my computer and everything went fine. After surfing the web for a little, I decided to take the SSD and HDD and put it in the case. Put the SSD and HDD in the case but the problem came back again and idk what to do )-:
