its not on long enough to check cpu temp, but its usually around 50C. The shutdowns have been happening for the past couple months, so would you think that this is a coincidence? That the one time i take off my cpu, the power supply stops working?
best bet would be find a spare psu and plug it in. if it powers on and keeps on then check all your bios settings. Just reset your bios settings and try to restart it again. if all works then BAM you found your issue.
