Hello! The other day I was on my Windows PC and the power went out, while I was using it. After this, it turned on then back off very fast. I thought it would be no big deal. When the power came back on, I tried booting up my PC, but it would not boot. Just a black screen. There is also an orange light on the motherboard that normally pulses at all times, now it isn’t.I ’m assuming it has something to do with the power going out and then flickering. Is there anything I can do to fix this?
Thank you!
 
could be the power supply in the PC.
laptop or desktop?

have you tried putting the power cord into another outlet?
if using a power board, change it and see it that helps.

otherwise, the good money is on the power supply unit.
 
It’s a desktop. I’ve done that. I’m not sure what else to do. Do you think i need to get another power supply? Or is the motherboard messed up as well? Is there some way to test these components?
 
hopefully if it is the power supply unit, when it went, it didn't take out anything else.
sadly, the best test is a replacement part.
while the chances are good it may only be the PSU, if you could get your hands on one just to test the theory, that would save buying one at this stage.

any chance the PSU has a LED on the back of it (most don't), and can you hear the PSU fan going at all?
