About a month ago there was a power surge/outage at my parents' house when the oven element decided it no longer wanted to work and took out all the rest of the electricity with it, I can't remember if my computer was plugged into a surge protector or not but it was on at the time and when I came to turn it back on later I discovered it wouldn't turn on. I've set it all up again having moved house and replaced the power supply as that's a fault I've had twice in the past but it still won't turn on. The monitor works fine, I've checked that, I'm pretty sure the HDD is ok, but even if it wasn't I'd still get bios and then an error I think? I plugged a linux live USB into it on the off chance it might work but nope. It's not even attempting to start, there's no movement or sound from anything anywhere which is a bit concerning and I'm slightly worried it may have fried my motherboard?
