Hi all! I just built my first PC from scratch almost a week ago. It ran without an issue for a couple days after I got it up and running. Now it shuts itself off and won’t turn back on unless I unplug the power cable for a few seconds. The time it takes to shut off decreases each time it gets running again – it starts around 30 minutes for the first time.
I reinstalled everything except for the CPU (and heatsink) and double checked the connections. Everything registers in the BIOS the way it should. The voltage looks good from the BIOS but the 12V rail is reading just over 8V from hwmonitor (haven’t verified with voltmeter). Temps don’t exceed 36C on anything.
I suspect that the PSU is to blame, but I wanted to ask you folks first. Any ideas?
