So, last night there were 4-5 different power blackouts in my area due to heavy rain. After the first one, however, my computer stopped turning on. The motherboard lights aren't coming on (they're usually on when the PSU is on) and pressing the power button does absolutely nothing. I've only really tried holding the "clear cmos" button on the backpanel for about 10 seconds so far. Did the blackout damage my system? What components could it have damaged and how could I test for them?
