My computer, the lights turn on, but won't start

There was recently a power outage in my area, and now my computer won't work, I click the power button, and the light turns on, and the fans start, but the screen won't turn on, and the lights on my keyboard don't turn on

Re: won't start

Looks like some hardware damage. Could be the PSU, the motherboard or anything on it (CPU, RAM). Time to find a repair shop.

CPU should be fine

most likely just a PSU

Mainboard or PSU DC voltage rails or both .keyboard lights dark is the tell they aren't geting DC volts if they arent overvolted and gone that is unlikely here try it on another PC .

I have seen that mainboards and or PSU can do that and a DVM can narrow it down in some minutes ,so can swapping in another compatible PSU but with a DVM you have to know what and how to check the DC voltage rails

Usually something like that just takes out the power supply. In 2012 I had a one year new new but out of warranty Core i7 HP Pavilion Mid Tower go down like that from an open neutral utility service line power surge and ultimately after checking the PSU vacancy with my DVM and swapping in an ancient P4 PC ATX v12 PSU for a few days I ultimately put in a new $65 cooler master 800W PSU .
and it was fine and they paid me for a while brand new HP core i7 PC since it was on the utility side ha ha ha .
