So I just got around to delivering my old parts to my flat mates empty case in the hopes of setting up for him a basic Half Life 2 playing rig to find that it doesn't turn on! Everything is plugged in correctly, however the only suspicious thing that has caught my eye so far is that when plugged in (cable into the PSU) no fans on the PSU or the motherboard/chassis actually whirl like I have been accustomed to when plugging PC's into an active mains socket. Am I correct in thinking if there is "juice" then when the pc is first plugged into the mains the fans should spring to life for at least an instance? If this is true it will narrow done the conflict to the PSU and hopefully I can get it sorted by the end of the week! Or could it be a fault with the motherboard which I'm a bit weary on as it was working the morning before I took it out of my old PC and into his.
Cheers for any advice you guys can give!
