Possible PSU failure; I'm not sure.
I have a System hear that is not powering up. I have checked it with a PSU Tester and all the voltages are showing as normal \ fine. I have changed the Power Lead and also moved it over to another socket out let but the acutall PSU it self on the back is showing a flashing LED light and not powering up when I'm switching the PC on.
The PSU is just a bog standard PSU that came with the Tower. Nothing custom or installed by my self.
I'm completely stumped. The Voltages are fine, The socket if fine, and their is power but I can't think of anything other than a PSU failure it self.
