I have a computer that's been built by my brother, filled with brand new components, the case is second hand. It powered up once with everything apart from graphics card installed. When that was installed and connected to a monitor nothing happens. Now it won't power up at all, even without graphics card.
Either something has been installed incorrectly or a new item is faulty, however he can't identify the fault.
It seems like a waste of money send it for a service, so someone can tell me a component is faulty... or maybe it just needs a tweak.
I'm clueless, any advice would be greatly appreciated
