Hi, I built my PC on Sunday October 28th. It was working fine for an hour or two, then it started to freeze on the Windows loading screen and after a hard reset I would get a black screen for a couple of minutes then my desk top will load. I have a brand new z390-a Asus motherboard, I-5 9600 k, 2 860 250 GB ssds and one 4 TB Barracuda hard drive and and the OS is booting off of one of the 860 ssds. My brother and I cannot figure out why it keeps happening. We've updated everything. And when we run the windows Diagnostics it says that everything's A-OK. If someone can help that would be awesome thank you
