On Monday I added a further hard-drive to my home built (PCPro spec) PC. On putting everything back together I go to switch on and nothing. Just the slightest hint of a couple of fans moving momentarily but certainly no more than a few millimetres. Now as the PSU is only 3 years old it seems unlikely it has packed up already and has never previously been an issue. So what else might be the cause? Any thoughts anyone.
