Hello, I woke up one morning to find my PC not turning on, I suspected it was the PSU as the computer was receiving no power. After receiving a replacement PSU the system still doesn't even budge to turn on, none of the fans responsive, no bios or post, just the blinking PWR button on the mobo.

Any help what so ever would be appreciated

I've rebuilt the system outside of the case. Still nothing, the PWR button light blinks green when PSU is switched on by switch, and carries on blinking every 6 seconds.
