Hi, I have just spent the last three days building my first htpc...I took every precaution possible and carefully connected everything up and then this afternoon I "hit the on switch" expecting something to happen...but nothing....not even a peep...why...have I been bad in some previous life. I'm sure I dont deserve his. ok so you can feel the disappointment here so please someone help me . Is it as simple as a duff PSU...it is a horrendously expensive SilenX 450W jobby so I would have thought for just shy of 100 quid it might just work off the bat. Is there something else I am missing? If not even the PSU fan is working does that automaticxally mean it is the PSU which is faulty. ...and before anyone asks...yes I sis plug it in and ensured the socket was turned on...also tried various sockets and also tried different lead into the PSU.
