Hello, new here! I've spent over a month looking for a solution to this "new" build problem.... I've had the MOBO back and forth to the supplier and finally got a BIOS upgrade.. so now the pretty lights on the MOBO are illuminated.. but that's it. I've bought a 2nd stick of RAM from a 2nd vendor to check that - no change. Can't afford a new CPU but don't think that's at fault and this is the second of the same brand PSUs I've tested it with. Is there a secret switch somewhere? Or a plastic "try-me" tag like on my lads toys at xmas? (Erm, lol [ish]). Help, please!
