I'm not especially familiar with tackling hardware issues, so I am hoping someone might be able to point me in the right direction.
I have (or rather someone else does) a desktop PC, an MPC ClientPro, which was working fine, and then one day - possibly (but only possibly) after some sort of electrical interference overnight - decided not to power on next day; no lights, no noise, just nothing at all - completely dead. I guessed it might well be the power supply, but thought I'd check inside first for anything obvious. So, I checked that the start button cable was firmly in the motherboard, blew out a load of dust, from around the fans etc, and plugged the power cord in. Still nothing, but seeing as I had it opened, I notice a green LED on the motherboard, when I turned the power on. (I honestly can't recall if that happened when I pressed the power button the computer, or when I stuck the power cord in the PC). So, given that it seems to recognize some form of electricity, is it still reasonable to assume that it's the power supply at fault?
Any suggestions very much appreciated.
