Hi Leon,
It does sound like the power supply is faulty. I've had 2 of those 'bump the pc' issues over the years and both times it was the power supply. They are not that hard to replace but sometimes a bit fiddley. If you do find out that is the issue and want to tackle it yourself, just check all the connection are correct with the new one.
Good luck
Cheers,
Damien
