Hi Kaden, I do appreciate your help
OK, not the HDD, deff not the fan, its VERY clean and runs fine....
Probably the PSU as it does seem strange that if you plug anything in (taking extra load) like the HDMI or the controller (via the USB lead) it kinda dies, doesn't go standby or anything, you just hear the relay CLIK and everything is off.... you have to leave it a minute or two then re-connect the power lead before you can get anywhere, hate giving up on things... but this is close.... I have seen a few on ebay and apparently it's a common problem... not found THE FIX to said "COMMON" problem as yet ?
....any clues sire ????
