I bought an MSI Media Live PC about 6 months ago, all worked fine until a few weeks ago (had been sat not used for about a month), it now won't switch on. I've checked out the power supply, I triggered it by shorting the correct pins and it spins up fine, so don't think that's the problem. I've also pulled the motherboard out of the case and disconnected everything apart from the power supply and power switch, when I push the power button the power supply fan does about 1 rev and then stops. I suspect it's the motherboard at fault, anyone got any suggestions of things to try before I send it back?
