Are you for real I really hope your not being serious.

MI5 wrote Recently I built a PC, everything went fine, powered up first time, about 30 minutes later, I had to reset the PC, so all the Drivers could finish installation & updates could be installed, but once I turned it off, it wouldn't power back up & I have no idea what I've done.

I have tried rebuilding the PC from scratch, still nothing, I've tried the PSU in another PC, it works fine.

Any help would be great

Thanks.

Something similar happened to me. check the wire that goes to the power button. try to "hotwire" the pc with a screwdriver. (touch it to the pins on the mobo)
