Out of the blue ...Suddenly there was no power ... no fans ...but after pressing the power button there was a flash of light on removing finger.Any ideas please?
Dead PSUUnplug mains, try the fuse.Next look inside case to see if a wire has come loose. Next if fuse has gone on main plug, try using another fuse, if fuse still blows try another PSU
madboy33Thanks for the response. It is not the fuse and I can't see any loose wires (other than the normal power spares).Can one rule out PSU because the lights blink when taking finger OFF the front power button. These are actually on a 4xUSB panel? If not PSU is mobo the next option?Any comments appreciated.
PSUs amy fail totally, or on just some of their outputs - so even if you get some lights flashing, it may be the PSU.The next major suspect, as you rightly guess, is likely to be the motherboard.
Try a PSU first
Do not connect test a PSU that does not have a load. It should be connected to MOBO to test the PSU so don't try plugging a new one in and switching on as they are meant to only work when connected
