Hey all, I need your expert advice here. I'd so oh the last month or two this has been happening at random times. During idle times when I'm browsing the web, have iTunes going, my screen will flash and I can hear my GPU fan get louder. I looked at my temps and it was getting higher by the second. Every time this happens, I have to reboot and it goes back to normal temps around 38C when Idling. Though not sure if my CPU is doing the same thing. Is this a sign that I need a new PSU? I have a stock one that came in my Acer system. I know I'm borderline for min psu requirements for my GPU so that's why I'm asking. Thanks!
