Have just swapped corsair aio for an air cooler on a MSI GD65 P67 board - which involved removing the board and re-building the whole thing.
Pressed the start button - nothing. Double/triple checked all connections in place - no apparent problems - Tried again - nothing.
Noticed that the board has what I can best describe as 'on' , 'reset' and overclock(turbo) buttons so decided to try the on button - great it all starts and appears to be running correctly.
EXCEPT realised that the power button on the case is still not working and pressing and holding for 5 secs (tried 30secs! and a few more attempts) does not power down i.e. the button does appear to be wholly ineffective.
The reset button works as you would expect although I have not tried to re-set from start so do not know if I could use as a substitute start button.
To me it boils down to a button/case or motherboard problem but would appreciate advice of others 1
For myself I think it is probably a case/button issue but am wary of spending on a new case because I am simply misinterpreting the problem.
Thanks , in anticipation.
BTW - the case is a cheap Silverstone job - PO5b or something like.
