I've got a weird one for you guys.
I built a PC right at the end of last year, and it's been a kinda bumpy road. I have a weird issue with restarts. Sometimes when I restart, my 1080p 144hz monitor gets set down to 480p or 768p, and didn't recognize the right refresh rate options. It seems to happen completely randomly. The first time it happened, I was overclocking my CPU, but I've had it set to stock (I even reset my CMOS) and nothing fixed it. Nothing at all is overclocked. I ran 2 passes of Memtest and no errors. The only way to fix it is to leave my computer off for a few minutes.
Sometimes my PC used to not boot at all on restart, but it hasn't happened recently. I'm not sure if that has been fixed or not/
