NZXT Phantom 820 tower chassis power bottom faulty

[edfan5150]

The power button on my son's NZXT Phantom 820 tower has developed an intermittent fault: Sometimes will not power up computer, other times my son holds down power bottom & flicks wall socket switch on & off with foot until he manages to get it to power up! Any suggestions would be appreciated. Computer is our second self build & has worked fine for 6 months!

Are 100% sure the switch is the issue? If there is a Reset switch, have tried using it instead of the Power switch?
