been through this

yeah i have been on the look out for those kind of manufacturer problems... not found any evidence online... mounting studs and jumpers have all been thoroughly checked both by me and by the shop...

when the system powers on (has not done for the last 3 days) but when it does... this rules out any misplaced jumper or mounting stud holding back start up...

this ALWAYS happens when i remove mains power for anytime... it SOMETIMES happens when i shut down the pc but leaves mains on...

basically if i remove mains power from the system and reapply it... the motherboard seems to be unable to send the signal to the psu to start the system up when i press the powerswitch.... which i think is a fault on the board...

i could try what you are suggesting... power up outside the case... never done this before because i dont have the means of a powerswitch...

whats the best way to power up outside the case without a powerswitch?
