Every hour or so while I'm playing VR, my Oculus Rift S (This only happens under heavier workloads) will completely freeze it's screen. I come back to my computer and I see that everything is also frozen. I click buttons and my mouse with no results and am forced to reset my computer every time. I have tried all the basic solutions such as driver updates, de-fragmenting, and checking for lost files. I want to start troubleshooting hardware but I don't know where to look first. I don't have extra motherboards or gpus to test with however. I was hoping some experts would know what could be the problem (drive, gpu, mb, or ram?). Nothing is even close to overheating. My specs are below, Thanks for the help.
CPU: i7 6700, GPU: GTX 960 (I know its below the recommended but I still get normal fps) RAM: 16GB 1666mhz MB: MSI Z-270 pro gaming AC, Two HD's 1TB SSHD 7200, 2TB 7200, PSU: Seasonic Gold 750w
