At random moments, my monitor and usb devices lose power for a small amount of time. My whole pc does not turn off, as my case fans and gpu never turn off. When the problem occurs though, my motherboard turns on its 3 red lights after as if it is just turning on. It restarts my pc and brings me back to logging in to desktop. I'm unsure if it is a motherboard problem, but I think it could be my power supply. All drivers are up to date for all components. I have a cx650m psu which makes more than enough power for my hardware, but it is definitely getting old. Any help appreciated thanks.
