A little over a year ago I built a new PC for VR gaming (https://pcpartpicker.com/list/pBsVsY) I have also added a USB card and a sound card. I basically use this system exclusively for VR gaming and a little standard gaming. Recently I have had some strange crashes but have started to notice other issues. When I try to put the computer to sleep the system freezes up. Shutting down the computer has always worked until last night where is seemed to just be restarting instead of shutting down. Lastly, my mobo sound doesn't seem to work. I have tested the speakers and they are fine but cannot get sound through the mobo. I do get sound through the video card so I have sound on my headset or my TV but not my external speakers. I am not sure what is going on but hopefully someone here can help. I hope I put this in the right place to post this.
